What you describe needs continued investment into datacenters. The hardware doesn’t last forever (avg. life expectancy is somewhere around 6 years iirc), and running that hardware also isn’t free at all. Add to that that you can nowadays run Cyberpunk 2077 on medium detail with 60 FPS on a freaking Android Phone with FEX and Proton, and personal computing is far from dead, regardless of what they want.
