I think technology is only one way of expanding markets indefinitely, albeit one of the most beneficial when it happens.

Unfortunately capitalism's need for infinite growth is nigh unstoppable and it always finds a path. If there aren't enough startups, technological advances, or similar we see things like private militaries, Banana Wars, buying elections, private prisons, over leveraging, etc. Capitalism has to have an outlet and we are at its mercy in that sense.
