I agree. Browser APIs don't have as much coverage as native APIs, but I would say that by far most UIs should be in the browser nowadays.

Quake can run in the browser, so in my opinion so can the likes of Photoshop. Maybe the latest AAA game is a different beast, but that's a tiny edge case.

Websites instead of apps on mobile is something that basically always sucks, but I don't see the same on desktop.

Just build your UIs in WASM already. :-)

It's been done.
