I think when this was written everything seemed pretty great. In 3 years it all looks like '90s to me, crossing his criticality into non-risky bets and slanting non-tech plays as some kind of tech-level margin plays (real estate, kitchens, delivery etc). There's a chance some of these non-tech plays turn out to be great monopolies (primordial Amazons) on a very extended time scale, but they are effectively using investor greed/incompetence to do so.
