Well, when you can put computing power on par with a whole cloud in a single box, which you can nowadays, the equation changes again. 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.
