Losing your phone or having it stolen can feel like a nightmare, especially when you consider the treasure trove of personal information stored on your device. From banking apps and email accounts to social media profiles and payment methods, smartphones contain virtually our entire digital lives. When a criminal or pickpocket gains access to your phone, they potentially have the keys to your identity, finances, and online presence. However, acting quickly and methodically can help minimize the risks and protect you from identity theft and financial fraud.
The reality is sobering, criminals with access to your phone can make unauthorized purchases, hack into your accounts, and even steal your identity to open new credit lines in your name. But by following these nine critical steps immediately after discovering your phone is missing, you can significantly reduce the potential damage and protect your most sensitive information.
Before taking any drastic measures, start with the obvious: try calling your phone from another device. You might hear it ring nearby, or someone who found it might answer and be willing to return it. If this doesn’t work, turn to your phone’s built-in tracking capabilities.
For iPhone users, Apple’s Find My service allows you to see your device’s location on a map, play a sound to help locate it, and even view its last known location if the battery has died. Android users can access Google’s Find My Device with similar functionality. Both services can be accessed from any computer or other device by logging into your Apple or Google account. These tracking tools not only help you locate your phone but also provide remote control options that become crucial if recovery seems unlikely.
If you can’t physically retrieve your phone or suspect it’s in the wrong hands, immediately lock it remotely. This creates an additional barrier between a potential thief and your personal information, preventing access to your apps, messages, emails, and saved payment methods.
Both iPhone and Android devices offer remote locking capabilities through their respective tracking services. You can also set a custom message to display on the lock screen with your contact information, which could help if someone honest finds your phone and wants to return it. For iPhone users, this means accessing iCloud.com or using the Find My app on another Apple device, selecting your lost phone, and choosing “Mark as Lost.” Android users can visit android.com/find, select their device, and choose “Secure Device” to lock it and display a custom message.
While law enforcement may not actively search for your stolen phone, filing a police report creates an official record that can prove invaluable if you need to dispute fraudulent charges or deal with insurance claims. When you visit your local police department, bring as much information as possible about when and where your phone was lost or stolen.
Having your phone’s IMEI number (International Mobile Equipment Identity) or serial number available will strengthen your report. You can usually find these numbers in your phone’s settings, on the original packaging, or through your carrier’s account portal. This documentation becomes particularly important if criminals use your phone to commit further crimes or if you need to prove to financial institutions that fraudulent activity resulted from theft.
Your next call should be to your mobile carrier to suspend service on your stolen or lost device. This prevents unauthorized calls, texts, or data usage that could result in unexpected charges on your bill. More importantly, it helps protect your account from being hijacked or used to access two-factor authentication codes sent to your number.
Most major carriers can also blacklist your stolen device, making it much harder for thieves to use even if they manage to bypass the screen lock. When you contact your carrier, ask about temporary suspension options if you’re still hoping to recover your phone, or proceed with permanent cancellation if you’re ready to move to a replacement device. Many carriers also offer insurance programs that may help cover the cost of a replacement phone.
Even with remote locking enabled, sophisticated criminals may find ways to access your stored information. This makes securing your online accounts one of the most critical steps in protecting yourself from identity theft. Your phone likely has saved passwords, active app sessions, and stored payment information that could be exploited.
Start by changing passwords for your most sensitive accounts, particularly email, banking, and financial services. Focus on creating strong, unique passwords that would be difficult for criminals to guess. McAfee’s Password Manager can secure your accounts by generating and storing complex passwords and auto-filling your info for faster logins across devices. Next, remotely sign out of all apps and services that were logged in on your stolen device. Most major platforms, including Google, Apple, Microsoft, and social media sites, offer account security settings where you can view active sessions and log out of all devices remotely. This step is crucial because it prevents thieves from accessing your accounts even if they bypass your phone’s lock screen.
Consider this an opportunity to enable two-factor authentication on accounts that support it, adding an extra layer of security for the future. While you’re at it, monitor your online and financial accounts closely for any suspicious activity, unauthorized transactions, or login attempts from unfamiliar locations.
Your stolen phone likely contains mobile payment apps like Apple Pay, Google Pay, or individual retailer apps with stored credit card information. Criminals can potentially use these payment methods to make unauthorized purchases, so removing them quickly is essential for protecting your finances.
For Apple Pay users, marking your device as lost through Find My iPhone will automatically suspend Apple Pay on that device. Alternatively, you can manually remove payment methods by signing into your Apple ID account at appleid.apple.com, selecting your lost device, and choosing to remove all cards. Google Pay users should visit payments.google.com, navigate to payment methods, and remove any cards linked to the compromised device.
Don’t stop there – contact your bank or credit card issuer directly to alert them about the potential for fraud. They can freeze or cancel the cards linked to your mobile payment apps and monitor for any suspicious transactions. Review your recent statements carefully and report any charges that weren’t made by you. Most financial institutions have straightforward fraud dispute processes and will work quickly to resolve unauthorized transactions.
When all hope of recovering your phone is lost, remote data erasure becomes your final line of defense against identity theft. This nuclear option wipes all stored data, settings, media, and personal information from your device, ensuring that criminals can’t access your photos, contacts, passwords, financial information, or any other sensitive data.
Both iPhone and Android devices offer comprehensive remote wipe capabilities through their respective tracking services. For iPhone users, this means accessing Find My and selecting “Erase iPhone,” which will restore the device to factory settings and remove all personal information. Android users can accomplish the same thing through Find My Device by selecting “Erase Device.”
Keep in mind that once you erase your phone remotely, you’ll lose the ability to track it further, so make sure you’ve exhausted all other options first. However, the peace of mind that comes from knowing your personal information can’t be accessed often outweighs the slim chance of recovery.
Criminals with access to your phone may attempt to exploit your personal relationships by impersonating you in messages or calls to your contacts. They might send urgent requests for money, ask for sensitive information, or attempt to trick your friends and family into various scams using your trusted identity.
Reach out to your closest contacts through alternative communication methods to warn them that your phone has been compromised. Let them know to be suspicious of any unusual requests coming from your number and to verify your identity through a different channel if they receive anything questionable. This proactive step can prevent your loved ones from becoming secondary victims of the crime.
Once you’ve accepted that your phone is truly gone, it’s time to focus on getting back online securely. Check with your mobile carrier about replacement options, as some plans include insurance coverage that can significantly reduce the cost of a new device. Even if you don’t have insurance, carriers often offer payment plans for replacement phones.
When you get your new device, you’ll be able to restore your data from cloud backups like iCloud or Google Drive. This is why maintaining regular automatic backups is so important – they ensure you don’t lose photos, contacts, app data, and other important information permanently. During the setup process, take the opportunity to review and strengthen your security settings based on what you’ve learned from this experience.
The theft of your phone represents just one potential pathway to identity theft, but it’s often one of the most impactful because of how much personal information our devices contain. While following the steps above can help minimize immediate damage, comprehensive protection requires ongoing vigilance and professional monitoring services.
McAfee’s Identity Protection offers multiple layers of defense that can alert you to potential identity theft before it becomes a major problem. Through comprehensive identity monitoring, McAfee identifies your personal information across the dark web and various databases, providing early warnings when your data appears in places it shouldn’t. This includes monitoring of social security numbers, government IDs, credit card numbers, bank account details, email addresses, and phone numbers – often alerting users up to 10 months earlier than similar services.
The credit monitoring component keeps watch over changes to your credit score, reports, and accounts, sending timely notifications when new accounts are opened, credit inquiries are made, or suspicious activity is detected. This early warning system can help you catch identity thieves before they cause significant financial damage. Perhaps most importantly, if you do become a victim of identity theft in the U.S., McAfee provides up to $2 million in identity theft coverage and restoration support for select McAfee+ plans.
While no one plans to have their phone stolen, taking preventive measures can significantly reduce the potential impact if it happens to you. Enable device tracking features like Find My or Find My Device before you need them, and make sure you know how to access these services from other devices. Use a strong passcode or biometric authentication that would be difficult for thieves to guess or bypass quickly.
Consider adding a PIN to your SIM card to prevent thieves from removing it and using it in another device. Maintain regular automatic backups to cloud services so you won’t lose important data permanently if your phone disappears. Most importantly, review and limit the amount of sensitive information you store directly on your device and consider using additional authentication methods for your most critical accounts.
Record your phone’s IMEI number and serial number in a safe place where you can access them if needed for police reports or insurance claims. These small preparatory steps can save significant time and stress if the worst happens.
Phone theft is just one of many ways criminals can gain access to your personal information and identity. In our interconnected digital world, comprehensive protection requires a multi-layered approach that goes beyond device security. Data breaches at major companies, phishing attacks, social engineering scams, and various online threats all pose risks to your identity and financial well-being.
This is where integrated protection services like McAfee+ become invaluable. Rather than trying to manage multiple security concerns separately, comprehensive identity and device protection provides peace of mind through continuous monitoring, early warning systems, and professional restoration support when things go wrong. The goal isn’t just to react to problems after they occur, but to prevent them from happening in the first place and to minimize their impact when prevention isn’t enough.
Having your phone stolen is stressful enough without worrying about the long-term consequences for your identity and finances. By following these nine essential steps quickly and methodically, you can significantly reduce the potential damage and protect yourself from becoming a victim of identity theft. Remember, the key is acting fast – every minute counts when it comes to protecting your digital life from criminals who might have gained access to your most personal information.

As another school year begins, the digital landscape our children navigate has become increasingly complex. With artificial intelligence tools now readily available and social media platforms evolving rapidly, considering creating a family technology pledge has never been more crucial, or more challenging.
Gone are the days when we simply worried about screen time limits. Today’s parents must address everything from AI-assisted homework to the growing threat of deepfake cyberbullying. The technology shaping our kids’ lives isn’t just about phones and social media anymore—it’s about preparing them for a world where artificial intelligence is reshaping how they learn, communicate, and express themselves.
Recent research from the Pew Research Center shows that 26% of students aged 13-17 are using ChatGPT to help with their assignments, double the number from 2023. Meanwhile, surveys reveal that between 40 and 50 percent of students are aware of deepfakes being circulated at school. These statistics underscore a reality many parents aren’t prepared for: our children are already immersed in an AI-powered world, whether we’ve given them permission or not.
The key to successful digital parenting in 2025 isn’t necessarily about banning technology—it’s about having intentional, educational conversations that prepare our children to use these powerful tools responsibly. We need to acknowledge that technology is here to stay, so the best thing we can do is accept it’s here, educate our kids on how to use it safely, and introduce boundaries and rules to help keep them protected.
For any pledge to be effective, lasting, and conflict-free, we need to shift the focus from simply setting rules to creating an open, constructive dialogue that helps all family members use technology in healthy ways. The most successful technology pledges are created collaboratively, not decided without collaboration. This ensures everyone feels included and that the guidelines reflect your family’s unique needs and values.
The most important consideration in tailoring a pledge to your kids’ ages and maturity levels, and to your family’s schedule. There’s no point making pledges that don’t reflect your children’s actual technology use or your family’s realistic expectations. Remember, this is about starting conversations and creating a framework for ongoing dialogue, not a rigid set of rules that’s destined to fail.
One of the biggest changes in recent years is the need to address AI tools like ChatGPT, Claude, and other learning platforms. Rather than trying to catch assignments written by AI, many schools are now launching programs that include AI Learning Modes, recognizing that these tools can be valuable when used appropriately.
The benefits of AI assistance in education are significant and shouldn’t be ignored. AI can serve as a personalized tutor, explaining complex concepts in multiple ways until a student understands. It can help students with learning differences access the curriculum more effectively, and students working in a second language can use these tools to level the playing field. When used properly, AI can enhance critical thinking by helping students explore different perspectives on topics and organizing their thoughts more clearly.
However, the risks of over-reliance on AI are equally real and concerning. New research has shown that overreliance on AI might erode our ability to think critically, and critical thinking skills are essential for success in the real world. Students may become dependent on AI for basic problem-solving, missing opportunities to develop their own analytical skills and unique voice. Academic integrity concerns arise when AI does the work instead of supporting learning, potentially undermining the entire educational process.
Your family technology pledge should address these nuances.. Children should understand that they will use AI tools to enhance their learning, not replace it. This means always disclosing when they’ve used AI assistance on assignments, using AI to explain concepts they don’t understand while still working through problems themselves, and never submitting AI-generated work as their own original thinking. They should learn to ask AI to help with organizing thoughts, not creating them, and use AI to check their work for errors while ensuring the ideas and solutions remain their own.
The rise of AI-generated content has created unprecedented risks for students, particularly regarding deepfake technology. Research shows that girls are most often targeted by deepfake images, and for victims, the emotional and psychological impact can be severe and long-lasting. What’s particularly alarming is that one photo posted online is all that’s needed to create a deepfake, making this a potential risk for every student.
Parents should help their children become mindful of what photos they share on social media, understanding that any image could potentially be misused. Children must understand that they should never participate in group chats or conversations where deepfakes are being shared, even passively. They need to recognize that creating deepfakes of others, even as a “joke,” can cause serious psychological harm and that possession of manipulated sexual imagery involving minors is illegal.
Creating a family technology pledge isn’t about limiting your child’s potential—it’s about empowering them to navigate an increasingly complex digital world safely and ethically. The emergence of AI tools and deepfakes is forcing families to have important conversations about ethics, empathy, and responsibility that previous generations never had to consider.
The goal isn’t to create a perfect document that anticipates every possible scenario. Instead, it’s to establish a foundation for ongoing dialogue about how technology can enhance rather than detract from your family’s values and your child’s growth into a thoughtful, responsible digital citizen. To help parents and guardians start discussions, we’ve created a first draft Technology Pledge that you can use to start a discussion with your family.

The digital landscape will continue to evolve, but the fundamental principles of kindness, honesty, and critical thinking remain constant. By creating a thoughtful technology pledge and maintaining open dialogue about digital challenges, you’re giving your child the tools they need to thrive in whatever technological environment they encounter. Start the conversation today. Your child’s digital future depends on it.

October marks Cybersecurity Awareness Month, and this year’s message couldn’t be clearer: small actions can make a big difference in your online safety. As cyber threats continue to evolve and become more sophisticated, the importance of taking proactive steps to protect yourself, your family, and your personal information has never been greater.
The 2025 theme, “Secure Our World,” focuses on simple yet powerful steps that anyone can implement to boost their digital security. At the heart of this year’s campaign are the “Core 4” essential practices that form the foundation of good cybersecurity habits. These four pillars represent the most impactful actions you can take to strengthen your digital defenses without requiring technical expertise or significant time investment.
The Core 4 principles serve as your digital security roadmap. Using strong passwords paired with a reliable password manager eliminates one of the most common vulnerabilities that cybercriminals exploit. When every account has a unique, complex password, a breach of one service doesn’t compromise your entire digital life.
Enabling multifactor authentication adds a crucial second layer of protection that makes unauthorized access exponentially more difficult. Even if someone obtains your password, they would still need access to your phone or authentication app to breach your accounts. This simple step blocks the vast majority of automated attacks and significantly raises the bar for would-be intruders.
Keeping your software updated ensures that known security vulnerabilities are patched as soon as fixes become available. Cybercriminals often target outdated software because they know exactly which weaknesses to exploit. By maintaining current versions of your operating system, apps, and security software, you close these doors before attackers can walk through them.
The fourth pillar, recognizing and reporting scams, has become increasingly critical as fraudulent schemes grow more sophisticated and prevalent. Today’s scammers leverage artificial intelligence to create convincing fake emails, text messages, and even video content that can fool even cautious consumers.
The statistics paint a sobering picture of today’s threat landscape. According to McAfee’s comprehensive Scamiverse Report, 59% of people globally say they or someone they know has been a victim of an online scam, with Americans facing an average of 14+ scams per day. Between February and March 2025 alone, scam text volumes nearly quadrupled, with almost half using cloaked links to disguise malicious intent.
The burden on consumers is staggering. Americans spend an average of 93.6 hours per year – nearly two and a half work weeks, just reviewing messages to identify fakes. This represents 1.6 hours per week spent verifying whether communications are legitimate, a significant drain on time that could be spent on productive activities. The emotional toll is equally concerning, with 35% of people globally experiencing moderate to significant distress from scams, and two-thirds of people reporting they are more worried about scams than ever before.
What makes modern scams particularly dangerous is their increasing sophistication and alarming success rates. When scams do succeed, 87% of victims lose money, with financial losses often being substantial. According to the Scamiverse Report, 33% of scam victims lost over $500, while 21% lost more than $1,000, and 8% lost over $5,000. Most troubling is the speed at which these crimes unfold – 64% of successful scams result in money or information theft in less than one hour.
Young adults face particularly high risks, with 77% of people aged 18-24 having been scam victims – significantly higher than the global average. This demographic encounters an average of 3.5 deepfake videos daily, compared to 1.2 daily for Americans over 65. The pattern suggests that digital nativity doesn’t necessarily translate to better scam detection abilities.
Today’s cybercriminals have embraced artificial intelligence as a force multiplier for their fraudulent activities. The accessibility of deepfake creation tools has democratized sophisticated fraud techniques that were once available only to well-funded criminal organizations. For just $5 and in 10 minutes, scammers can create realistic deepfake videos using any of the 17 different AI tools tested by McAfee Labs.
The scale of this threat has exploded exponentially. North America has seen a staggering 1,740% increase in deepfakes over the past year, with over 500,000 deepfakes shared on social media in 2023 alone. Americans now encounter an average of 3 deepfake videos per day, yet confidence in detection abilities remains concerning – while 56% of Americans believe they can spot deepfake scams, 44% admit they lack confidence in their ability to identify manipulated content.
The platform distribution reveals where consumers are most at risk. Among Americans, 68% report encountering deepfakes on Facebook, followed by 30% on Instagram, 28% on TikTok, and 17% on X (formerly Twitter). Older adults appear particularly vulnerable on Facebook, with 81% of those 65+ encountering deepfakes on the platform.
Understanding these evolving threats requires more than awareness—it demands tools that can keep pace with rapidly changing criminal tactics. Traditional approaches that rely solely on user education and manual verification are no longer sufficient when facing AI-generated content that can fool even security-conscious individuals. The challenge becomes even greater when considering that repeat victimization is common, with 26% of scam victims falling victim to another scam within 12 months.
People are developing some detection strategies, but these manual methods have limitations. According to the Scamiverse Report, 40% of people look for over-the-top claims like unrealistic discounts, while 35% watch for distorted imagery or suspicious website links. Other detection methods include identifying images that seem too perfect (33%), generic audio (28%), and audio-lip sync mismatches (28%). However, only 17% use more advanced techniques like reverse image searches to verify content authenticity.
The same artificial intelligence that enables sophisticated scams can also serve as our defense against them. Advanced security solutions now use machine learning algorithms to analyze patterns, context, and content in real-time, identifying threats that would be impossible for humans to detect quickly enough. This technological arms race requires consumers to leverage AI-powered protection to match the sophistication of modern threats.
McAfee’s Scam Detector represents a significant advancement in consumer protection, using AI-powered detection to identify and alert consumers of scam texts, emails, and AI-generated audio in deepfake videos across multiple platforms and devices. This technology addresses the reality that manual detection methods, while useful, aren’t sufficient against the volume and sophistication of current threats. When people are spending nearly 94 hours per year just trying to identify fake messages, automated protection becomes essential for reclaiming both time and peace of mind. With scam detector, you can automatically know what’s real and what’s fake.
McAfee’s Scam Detector works across three critical communication channels: text messages, emails, and video content. For text message protection, the system monitors incoming SMS communications and alerts users to potentially dangerous content before they open suspicious messages. This proactive approach prevents the curiosity factor that often leads people to engage with scam content—total protection with no guesswork.
Email protection extends to major providers, including Gmail, Microsoft, Yahoo Mail, and more, with lightning-fast background scanning that identifies suspicious messages and provides clear explanations of the risks involved. This educational component helps users understand the specific tactics scammers employ, from urgency language to impersonation strategies.
The scam detection capability represents a unique advancement in consumer protection, using AI to detect deepfake audio and other manipulative media designed to impersonate trusted individuals or spread disinformation. This feature addresses the growing threat of fake celebrity endorsements, manipulated political content, and fraudulent investment pitches that leverage realistic-sounding audio content and is trained to identify AI-generated audio.
In February 2025, McAfee Labs found that 59% of deepfake detections came from YouTube, more than all other domains combined, reinforcing the platform’s role as a primary source of deepfake content. This data underscores the importance of having protection that works across the platforms where people naturally consume video content.
Effective cybersecurity extends beyond scam detection to encompass all aspects of digital life. Password management remains fundamental, as weak or reused passwords continue to be primary attack vectors. A quality password manager not only generates strong, unique passwords for every account but also alerts users when their credentials appear in data breaches.
Virtual private networks (VPNs) such as Secure VPN provide essential protection when using public Wi-Fi networks, encrypting internet traffic to prevent eavesdropping and man-in-the-middle attacks. This protection is particularly important for remote workers and travelers who frequently connect to untrusted networks.
Identity monitoring services watch for signs that personal information has been compromised or is being misused. McAfee’s Identity Monitoring services scan for data breach databases, monitor credit reports, and alert users to suspicious activity across various financial and personal accounts. Select plans of McAfee+, can provide up to $2M of identity theft coverage. Early detection of identity theft can significantly reduce the time and effort required for recovery. Our identity monitoring service can notify you up to 10 months sooner than similar services.
Device protection through comprehensive antivirus and anti-malware solutions remains crucial as cyber threats continue to target endpoints. Modern security suites use behavioral analysis and machine learning to identify previously unknown threats while maintaining system performance.
While technology provides powerful tools for protection, human judgment remains irreplaceable in maintaining security. Understanding common social engineering tactics helps consumers recognize when they’re being manipulated, even when automated systems might not detect a threat immediately.
Scammers frequently exploit emotions like fear, urgency, and greed to bypass rational decision-making. Messages claiming immediate action is required to avoid account closure, unexpected windfalls that require upfront payments, or urgent requests from family members in distress all follow predictable patterns that become easier to recognize with awareness and practice.
Verification through independent channels remains one of the most effective defense strategies. When receiving unexpected requests for money or personal information, contacting the supposed sender through a known, trusted method can quickly expose fraudulent communications.
Cybersecurity is most effective when it becomes a shared responsibility within families and communities. Parents can model good digital hygiene practices for their children while teaching age-appropriate lessons about online safety. Regular family discussions about recent scam trends and security practices help create an environment where everyone feels comfortable reporting suspicious activity.
Workplace security awareness programs extend protection beyond individual households to encompass professional environments where data breaches can have far-reaching consequences. Employees who understand their role in organizational security are more likely to follow proper protocols and report potential threats promptly.
Community education initiatives, often supported by local law enforcement and cybersecurity organizations, provide valuable resources for groups that might be particularly vulnerable to certain types of fraud, such as seniors targeted by tech support scams or small business owners facing ransomware threats.
The cybersecurity landscape will continue evolving as both threats and defenses become more sophisticated. Artificial intelligence will play an increasingly central role on both sides of this digital arms race, making advanced protection tools essential for ordinary consumers who lack specialized technical knowledge.
Integration between different security tools will likely improve, creating more seamless protection that works across all devices and platforms without requiring separate management interfaces. This consolidation will make comprehensive security more accessible to consumers who currently find managing multiple security solutions overwhelming.
Regulatory initiatives may also shape the future of consumer protection, potentially requiring stronger default security measures on devices and platforms while establishing clearer responsibilities for organizations that handle personal data.
Cybersecurity Awareness Month provides an excellent opportunity to evaluate and improve your digital protection strategy. Start by implementing the Core 4 practices: use strong passwords with a password manager, enable multifactor authentication on all important accounts, keep your software updated, and learn to recognize and report scams.
Consider comprehensive protection solutions that address multiple threat vectors simultaneously rather than relying on piecemeal approaches. Look for services that combine device protection, identity monitoring, scam detection, and privacy tools in integrated packages that work together seamlessly.
Remember that cybersecurity is an ongoing process rather than a one-time setup. Threats evolve constantly, requiring regular updates to both your tools and your knowledge. Stay informed about emerging threats through reliable sources and adjust your protection strategies accordingly. McAfee delivers smarter protection against evolving threats.
The digital world offers tremendous benefits for communication, commerce, education, and entertainment. By taking proactive steps to protect yourself and your family, you can enjoy these advantages while minimizing the risks that come with our increasingly connected lives. Small actions today can prevent significant problems tomorrow, making cybersecurity one of the most valuable investments you can make in your digital future.

A proof-of-concept C2 framework that leverages the Google Calendar API as a covert communication channel between operators and a compromised system. And it works.
I took a bunch of bits and spread them out into ARM's neon registers and then did cool math on them to replicate the effects of an exclusive-or. It turned out to be way faster than I anticipated.
I then wrote unit tests that take advantage of generative testing with Quickcheck to make sure it actually works. I had never seen Quickcheck used to unit test inline assembly but it seems like no function using in-line assembly should ever not be covered by generative testing.
I love how readable this is. Honestly, the Rust tooling is so good that I never have to write assembly outside of Rust again.
I can't really think of a reason not to, don't say file sizes 😩.
