Sort of kidding, but I do suspect this cycle is over. There were a few years when "uber, but for..." or "an app for" or "a magic box that tests drops of blood which only has to do with the internet because we call it TECH" seemed to be the possible way to absurd riches, and while of course there is still money to be made in them hills I doubt the "throwing billions of dollars at a Bus, but with an App" thing will continue.
Of course I know nothing.
