I think ultimately the traditional corporation will die, and be replaced by DAOs and DACs, which can scale up to millions much easier. The problem I see here is tribalism. We've already seen what Bitcoin has done to the maximalists. These DAOs are going to turn into legit cults, and those cults are going to start doing some super fucked up shit and justifying their bullshit behavior.
That's when other DAOs will have to team up against these toxic cults, and inevitably I can see that leading back to a state of empire where many communities and currencies are bound by the rulership of a "higher authority". Whatever happens, gonna be super fucking weird. I can guarantee that much.
Obviously not gonna be all sunshine and rainbows.
