I'm completely convinced at this point that the "Command Palette" is a fundamental UI concept, and should be in all applications. It should also be a built in browser concept, there should be an API for websites to push items to the command palette ("new post", "muted words" etc)

genuine question. how do you debug code and ensure good quality when coding models spit out 1000s of lines i still cannot feel comfortable not understanding what every generated line does, reducing the productivity gains coding models should be giving me


this thread is what mass cope from legacy devs looks like. i talked to @FastCompany about why @garrytan's "AI slop" is actually the future of software engineering. the mass code review. the line-by-line gatekeeping. the "craftsmanship" that was really just slow iteration disguised as rigor - that era is over. and the engineers who built their entire identity around it are panicking. @gregorein brags about burning 3 billion tokens last year while dunking on garry for flexing lines of code. i've burned 6.6 billion in the past three months on codex alone. by his own logic, i'm 8x as credible. see how silly that sounds? yes, he found real issues. yes, they got fixed. that's exactly the point. karpathy's autoresearch proved this already - AI agents can solve very complex problems just by operating inside feedback loops, iterating to optimize a loss function. this is what software engineering is now - gradient descent. ship, measure, self-correct, repeat. all by the agent itself. this is the new startup playbook. your job isn't to review every line before deploy. your job is to build systems where agents observe outcomes - mrr, analytics, error rates, user behavior - and self-improve. the engineer's role shifts from gatekeeper to building the machine that builds the machine. you could run this level of audit (using AI) on any production site and find the same issues - most just don't have a billionaire CEO attached for virality. mocking the people who adapted is easier than adapting. but the craft is evolving whether you like it or not.



at this point i'm labeling this as performance art


The modern audience doesn't want you to accept this. But DOOM 1993 got everything right. No cutscenes. No hand holding. No corporate slop. Just brutal combat, genius levels and a metal soundtrack. Woke trash disappears within days. DOOM is still here.


@revenant_MMXX I don’t even smoke anymore But if weed puts you in “low power mode” instead of making you creative and stops your mind from going at 100mph Then it’s simply a sign of low intelligence







New Harvard Business Review research reveals that excessive interaction with AI is causing a specific type of mental exhaustion ( or AI brain fry), which is particularly hitting high performers who use the tech to push past their normal limits. A survey of 1,500 workers reveals that AI is intensifying workloads rather than reducing them, leading to a new form of mental fog. While AI is generally supposed to lighten the load, it often forces users into constant task-switching and intense oversight that actually clutters the mind. This mental static happens because you aren't just doing your job anymore; you are managing multiple digital agents and double-checking their work, which creates a massive cognitive burden. The study found that 14% of full-time workers already feel this fog, with the highest impact seen in technical fields like software development, IT, and finance. High oversight is the biggest culprit, as supervising multiple AI outputs leads to a 12% increase in mental fatigue and a 33% jump in decision fatigue. This isn't just a personal health issue; it directly impacts companies because exhausted employees are 10% more likely to quit. For massive firms worth many B, this decision paralysis can lead to millions of dollars in lost value due to poor choices or total inaction. Essentially, we are working harder to manage our tools than we are to solve the actual problems they were meant to fix. --- hbr .org/2026/03/when-using-ai-leads-to-brain-fry
