What worris me is not the price. It's that they mention it as a VSCode and VS feature, not as an API.

So what if I use Intellij? And worse, would it eventually kill Intellij?

? Did you even read the thread? It's about Copilot X, not Copilot. I use Copilot in Intellij daily, and that's exact what I'm worrying about: once MS's AI tools get big enough, they won't be so friendly to third-party IDEs.

It's not a stretch at all. Take a look at Copilot's homepage: https://github.com/features/copilot

> Keep flying with your favorite editor

Now, look at Copilot X's announcement:

> We are bringing a chat interface to the editor that’s focused on developer scenarios and natively integrates with VS Code and Visual Studio

> It recognizes what code a developer has typed, what error messages are shown, and it’s deeply embedded into the IDE.

It reads like "we're going to make AI a competitive advantage of VS and VScode." Of course they have the right to do it, I'm just saying I hate it.
