The point I'm making is that the processor doesn't matter much for gaming. An older computer can easily outperform a new computer if it has better components where it matters for gaming and casual use (SSD and GPU)
Cloud is limited by Amdahl scaling like everyone else, but distances and latencies between nodes are higher than in a single box. So instead you should think of time sharing like in the ancient days of supercomputers. Most tasks do not require neither massive parallelism of a cloud or cluster nor computational resources of a supercomputer.
If it's the question of ownership or price... Why not make it free? (Ignore this junk, make libreoffice etc. better.)
Just think of it as a PC that gets smaller. You cannot quite go super small unless you replace input and output devices. That will require more understanding of our own sensorium.
I last upgraded my CPU when it was nearing 6 years old, and I could barely tell the difference. My current CPU is nearing 5 years old, and if it wasn't for some of the enticing stuff AMD's recently put out, a CPU update wouldn't even be on my mind at all yet - in fact I was surprised to recently notice it had been more than 4 years since I last bought a workstation CPU.
I expect I'll buy 2 workstation CPU updates between now and 2030, 3 at most. and even that would take something special to drop in the early-to-middle of my normal timeline.
