I have a hard time believing this. The businesses employing us and the businesses competing with them will view handwritten code as an evasion of financial responsibility. That does not mean inevitability is positive or worth welcoming with open arms. But it is so inevitable at this point.
If this were true, then we wouldn't be seeing the correction to reasonable limits. While I generally agree not using LLMs is irresponsible and not viable any more, I have real doubts transformers will live up to the hype projections and the end of the profession. On the other side (with too much Ai coding), there are market penalties from the users (because of Ai mistakes).
