I can maybe believe that AI is writing 90% of the code within the AI labs using models rest of us cannot fathom. Although they stills seem to be hiring developers, so it is difficult to believe in real strongly.

But across the wide world of software? Everyone I see is just using AI as a compiler. They are still writing the code.

(Yes, compilers also write code, but I don't think that was the intent of the message. 90% of the software has been written by AI since we discovered the optimizing compiler if that was the intent.)
