Ok, the headline is a bit misleading: Microsoft isn't announcing a technological platform and toolset called CoreAI. They're announcing a business unit called "CoreAI – Platform and Tools". That's way less interesting .

The interesting part is that DevDiv and Office will be moving into it.

DevDiv is the one with ownership about VS, VSCode, .NET, Java, Go,...

Doesn't that make it even less interesting? If all those products are moving to this new division, then it cannot really be specifically about AI. It's just a routine corporate reorganization shuffle that happens to be using the buzzword du jour.

Lets say probably it is going to be a lot of AI down every single product that DevDiv is responsible for, most likely tied to OKRs.

Which will affect every single developer that works within Microsoft ecosystem of programing languages and tools.

If he's as successful with this as he was in his last venture, it won't be good.
