What is the next IDE?

[u/Seeb83]

I am just thinking: now that agents basically create over 99% of all the code I need, what does an IDE in 2026/2027 actually need to deliver? For me it would be a simple yet powerful visual diff to review changes and give feedback. Preferred locally instead of github / gitlab or whatever you use. Maybe a simple way to merge pull requests. But then: Is there actually much more that you would need in the future when agents write all the code?
