Elijah Wood and Christopher Cantwell are behind the reboot, so it should be quite fun to watch!
As a beside, I still think Halt and Catch Fire is the most underappreciated TV series ever!
The connections he makes later in the show from Headroom to modern Twitch streamers and saying "I want to see Max Headroom playing a video game" brought to mind modern vtubers. Certainly the tech is there now for someone to do a "real time" Max Headroom that actually is computer animated, though implementing the glitches would probably take some custom development of some sort.
That said, I think the proper approach for the show would be to do it in a retro-futuristic way and have it look much like the original media's perception of "the future" was. So as little CGI as possible, and all the TVs are still 4:3 tubes with big knobs. I highly doubt they'll take that approach, though; too much effort.
OBS and the StreamFX plugin would get you a hell of a lot of distance before needing too much custom code I imagine. Very nice bit of kit. Cool glitchy effects if you layer stuff up

The technology is definitively there.
I don't know if it's part of a joke, but he doesn't seem to distinguish properly between TV, broadcast TV, and cable TV. Specifically he talks a looong time about broadcast TV while calling it "Cable TV."
