Yea bitcoin will live for some amount of time but when people create robots then I think that we will have evererything what we want for free because we will have free energy and robot will work for us.
I don't get it... someone would still have to make those robots, keep them working, keep the code working, provide the material for robots to work with, sell those goods,.. if it comes to that that robots would be doing all of that, well then we might aswell be taken over by a hostile AI.
