nobody invest into a closed platform. i expect jetbrains to came up with something marvelous for ar/vr, but it will run on the upcoming version of Microsoft or HP glasses. you know, the only ones today that works just like an external monitor without a locked in ecosystem like apple or facebook.
the silly apps and games and such will net millions tho.
With tools like Remote Development extensions, VS Code already works superbly from a desktop or laptop, editing locally but using a remote machine (your own or some cloud thing) for the filesystem, git, compilation, dependency management, development server if its a web/network app, etc.
It also works pretty great on the iPad, other than the tiny screen (which yeah, is a dealbreaker IMHO, but wouldn't be on a many-screens device like Vision Pro).
It also works pretty fabulously in a web browser with that same setup (e.g. Github Codespaces, but you can roll your own, too).
I doubt we will see a great IDE that does everything locally on the device. But a great IDE client is eminently doable; it's basically already done.
The IDE is one application type where the tooling around offloading all the compute, and just keeping the UI local, has flourished. VS Code was the first to really do it so it was just as good or better as developing 100% locally. JetBrains is right behind them. Others are doing it too.
This was the only way iPad OS became usable as development machines. I don't expect there to be any good native IDEs for Vision OS, either.
But if you can deal with requiring a network connection, and using VS Code, you will be able to use Vision Pro to develop on a remote Linux machine (or Mac or Windows, if that is your thing).
Whether JetBrains will make an IDE client for it, enable third parties to make that, or not support it at all remains to be seen, I guess.
I was thinking of a VS code extension that lets me put files or directories “physically” on my desk. Itd be emulating the way that I read text books. Instead of keeping notes and bookmarks physically in the book I could drop sticky notes that represent files directly on my desk and show a preview by by just shifting my eye focus to the AR/VR note.
