The real world is where things that matter happen. Life, love, nature. The Web is distracting and loud, but it's a big, flimsy illusion. So I don't think there is any chance that Metaverse ideas will take off.
Regarding LLMs: good news! You can already run them at home. Check out KoboldAI. LLMs will become smaller as time goes on, too. There's lots of room for improvement in that field.
That 80% is important. We need non-techies, because they remind us that there's more to life than just computers.
