this is a very myopic view of the whole information tech revolution. I'd argue pretty much every business in the pre internet world had a component of information asymmetry as key enabler. whether you take stock brokerage or real-estate sale or arbitrage the bushels of wheat between rural & urban markets etc. Its easy to dismiss internet as porn glut but do you know that because of internet the way traditional arranged marriages used to happen in India has changed significantly. Its because earlier the 'market' was restricted to friends and family & now suddenly it is much bigger plus it has many more positive societal effects. do you know that middle-man cannot gouge the little farmer nearly as much because now the farmer has much clearer picture of going rates for grains in urban markets (An IIT Bombay prof actually created an app for that). I can go on.. But here's the problem, IMO, the effects of information asymmetry going away are very ephemeral (so far) because our society/government/law is still structured in very old school ways so it leads to something else with positional advantage expanding and eating away the gains (for instance google eating newspaper revenues).
I would even argue that a guy like trump is actually a product of information age as so long as its no longer possible to subdue any public information anymore, just try imagining Hitler create a mass apparatus like he did in information age. Trump just took this thing to next level of troll-ism.
one more thing, 'supercomputers in your pocket' are just getting started, just wait till you see the self driving cars on streets.
