Ask almost any software developer in big tech about their software and I’m sure they’ll praise it. Using it is a completely different story. I’m sure you think you’re having success vibecoding enormous and extremely complex problems, but I’d bet their either not extremely complex or it’s not working as well as you think.

This is misreading the original reply. An enormously complex problem is different from an enormously complex project. Complex projects can usually be decomposed into tasks of varying complexity, some of which I bet an LLM helps with.
