What I wonder then is...is it going to be the final word on the evolution of software development? AI has been trained on practices that were developed by people, by professionals and amateurs, by discussions on discussion boards, at tech events, through written books and then disseminated across open source projects. If no one writes code anymore then how to write and build software projects will never evolve beyond the 2022 state of affairs.

It seems like we have more innovation around "developer(=agent) experience" than ever. Look at all the people building various agent control plane systems, containers, isolation, issue tracking, project management etc.

innovation is about being able to reach for better solutions to problems where previously it would "take too long". e.g. DSLs.
