If that's actually the future of humans in software engineering then that sounds like a nightmare career that I want no part of. Just the same as I don't want anything to do with the gigantic mess of Cobal and Java powering legacy systems today.
And I also push back on the idea that llms can't troubleshoot and fix things, and therefore will eventually require humans again. My experience has been the opposite. I've found that llms are even better at troubleshooting and fixing an existing code base than they are at writing greenfield code from scratch.
