Goes right along with what Alan Kay has been saying - if you want to see the future in computing you can just buy it. Maybe today's analogue would be to give a smartphone a full reservation of a current supercomputer with 50 PFLOP/s and see what kind of application one could do by using computations on the phone's sensor? I'd imagine something AR related could be interesting, or applying some kind of NN training within seconds that would not be feasible on a phone today. Maybe throw in a quantum computer once supremacy over classical is achieved in some areas (which appears to be pretty close now, sidenote).
