Hey! Author here. That's actually a fair point — in hindsight, I see why the article comes off as 'because AI' and not having clear articulations on how the developer experience changes. The current set of changes we have are indeed incremental additions.
That being said, this is not accidental because we intend to not fundamentally disrupt the core workflows of today right away (as another comment said — IDEs of today are indeed built on years of user experience research). But we do see the capability to simplify or rethink the developer experience once AI is deeply integrated into every workflow. Its perhaps the same way I'd have never stated writing code as a problem, but after having used Copilot, I don't want to go back to not having it.
AI could provide some different views of project structure (not file/folder). AI could use existing IDE tooling?
None of this is a reimagining of the IDE, just some incremental additions to it.
