Commercially it would be more interesting to do active background removal. If every Youtuber has a professional background like a news anchor they would immediately look legit.

Pretty sure this is already a thing:

Green screen? Yes, it still requires some effort (buy and set up the actual screen, proper lighting), but I doubt a proper green screen setup would be outperformed by some AI system any time soon: Got a shitty cam? AI would have to fix that too. Shitty lighting? Still a problem after any background removal. And if you're gonna invest in those two things, might as well go for your green screen.

Background replacement is a commodity motion graphics tool. It has been around since the 90's, and exponentially better than this work here.

But against an arbitrary background?

I’ve seen real-time background removal for video and for still photos, but never gets it perfect. Too many artifacts.

That’s why the green screen is still utilized.

Yes, how do you think automated wire and stunt performer rigs are removed? Think of all the VFX you see; an immense amount of visual effects are animation basic principals applied to scraps of previous and past frames for the composition of the current frame.

zoom does this in real time, virtual background.

Came here to confirm this. Indeed Zoom does this in real time and replaces the real background with a virtual background or solid colour. We often use it at our workplace for fun.
