I'm still reviewing all the code that's created, and asking for modifications, and basically using LLMs as a 2000 wpm typist, and seeing similar productivity gains. Especially in new frameworks! Everything is test driven development, super clean and super fast.
The challenge now is how to plan architectures and codebases to get really big and really scale, without AI slop creating hidden tech debt.
Foundations of the code must be very solid, and the architecture from the start has to be right. But even redoing the architecture becomes so much faster now...
