Rockets have existed for more than 60 years alrrady, and have been used for almost exactly that for human travel. Smartphone "revolution" is a communications revolution, and not much more than that. Smaller and better performing computers, sure, it's nice. But it does not move the needle in civilization-development sense to me. As for rockets, they are hugely inefficient ways to transport large cargo, so if we want personal space travel, it'll have to be alternative technology or something really worthwhile in space for us to invest that much. If you are only talking personal small rocket launching, there's already a thriving community doing that.
