There was a time when software was closer to a freer market and there was room for anyone to be the next google. But this moment is deeply political, tactical, and the existing incumbents have so much power that learning the intricacies of their systems may be make or break for any of your goals (e.g. how to advertise on google, or get featured on the app store, how to secure a government contract, etc). It isn't a time for abstract generalities (like chasing "golden ages")
At least I don't think anybody is or should be asking how to build "great" stuff anymore, great hasn't won in many categories. Most things that were great were so only to gain a moat and then enshittify.
I'd be really curious if he's happy where the tech-world is now, if he sees it as an oligopoly, if he sees it as meritocratic, and if he sees any hope of it getting better.
