Most innovation is pointless, because a lot of it revolves around just making code easier to maintain and understand for humans, it’s not like you’re innovating radical new algorithms for a CRUD app or making performance modifications that people will actually notice.
But since AI writes everything anyway, innovations that improve “developer experience” are pointless, and all the other low hanging fruit has been taken.
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.
