Modern 3D games are local, so I’m not sure the point there. My point about 90s machines was that most business SaaS is not compute or data heavy unless it’s for a huge corporation.
As far as local data: my laptop has terabytes, my phone over a hundred gigabytes. I have fiber at home and have seen speeds approaching a gigabit on 5G.
It’s not that often that people sit down at entirely unfamiliar machines they’ve never used, log in, and try to do data intensive work. In that case I suppose an iCloud model of compute would be downloading a lot.
