🤖 LLMs Will Not Replace You
LLMs have taken over, your phone, your feeds, your job prospects, and most people still don’t get what they are. In just a few years, they’ve gone from fringe tech to gobbling up nearly half of all U.S. VC funding in 2024. Now they’re ghostwriting your LinkedIn posts, nesting in your OS updates, and spitting out weird Miyazaki-style images with mutant fingers. Everyone’s using them, but barely anyone understands them. This blog addresses why LLMs won’t replace you.

🤔 Why did Microsoft-backed $1.3bn Builder.ai collapse?
Builder.ai promised software as easy as pizza, but delivered a half-baked illusion. Launched in 2016 with big talk of AI-powered app creation, the company raked in $445M and hit a $1.3B valuation, backed by Microsoft and QIA. But by May 2025, it all collapsed. Turns out, the AI magic was mostly human effort from developers in India.

💰️ What's Working for YC Companies Since the AI Boom
Only 24 out of nearly 1,000 YC startups since the AI boom have hit Series A, just 2.4%. What’s working right now? Tools that help businesses run smoother, like internal automations, developer tools, and APIs. Think less “AI for dentists,” more “AI that helps devs and ops teams move faster.”.

📈 the Rise of Judgement Over Technical Skill
In a world where anyone can create anything with AI, the question isn’t “Can you do it?”—it’s “Should you?” Back in 1995, Brian Eno nailed this shift when he talked about how tools like Cubase replaced skill with judgement. Today’s AI tools are doing the same across writing, coding, design, and beyond. The real edge right now? It’s not talent, it’s judgment. This article looks at why your judgement matters more than ever.

💐 The Beauty of TanStack Router
Picking a router isn’t just a tech decision, it’s a foundational one. It shapes how your app works, how users experience it, and how you stay sane as it grows. Here’s why TanStack Router stands out, and why it might be the last router you ever need.

➡️ Remix waves goodbye to React
Heard the buzz about Remix leaving React? It’s true, sort of. Remix v3 is on the way, and it's shifting to a custom Preact fork to gain full control of the stack. React Router isn’t going anywhere, but Remix is aiming higher: rethinking what a web framework can be, with LLMs, Web APIs, and composability at its core. Here’s what you need to know.
