I needed to implement a complex feature. Not some CRUD UI thing , an actual algorithmic challenge that required thought. So I asked Gemini 2.5 Pro and Claude Sonnet 3.7 for help. Their responses? Absolute garbage. Both gave me completely useless suggestions. Wrong logic and inefficient approach. I had to solve it myself. From scratch. Let’s be honest: AI is great at stuff it’s seen before. CRUD apps, blog generators, UI clones , if there’s a million examples on GitHub, it can spit something out. But give it a real engineering problem? It folds instantly. This is exactly why AI demo videos always show the model building a to-do app, Snake game, or maybe some Pac-Man clone. Never anything with real architecture, edge cases, or novel logic. Because the moment it hits complexity, it chokes. We’ve reached a point where AI can help you build apps. But it can’t understand the product. It can’t design solid systems. It can’t debug subtle issues. It can’t adapt to unknowns. It can’t tell what matters in your stack. So the idea that “AI will replace all engineers” is lazy, hype-fueled nonsense. The people pushing that narrative either: • Never built serious software • Have something to sell • Or both Even the companies building these AI models know they can’t replace engineers, that’s why they aren’t doing it. Because they’d crash and burn. You don’t bet a billion-dollar product on hallucinated logic from a chatbot. What’s actually happening? AI is becoming a tool for engineers. A fast autocomplete. A brainstorming buddy. A doc parser. A unit test writer. But it’s not coming for your job. At least not if your job involves thinking. The more we integrate AI into real codebases, the more its limits show. The cracks widen. And the myth of the "AI engineer replacement" starts to look as laughable as "no-code will replace devs" in 2015. So no, AI won’t replace engineers. But engineers who use AI will replace those who don’t. Big difference.
