The fear is that capital will own all the means of production and services and what then of everyone else? Hope UBI is implement? Or perhaps become more self-sufficient? The hype around 3D printing seems to have died down. I guess a lot of grand visions weren't realised and a lot of cheap trinkets printed instead but it still contains an idea that should be nurtured: robotics and AI at the grass roots level. Don't let capital own all the means of sufficiency.
