"mass-production of humanoid robots is now inevitable in the next five years" My take? Probably not. It takes immense capital (which i guess, arguably, there is), and immense time and manpower to set up factories, research materials, Research and Development, manufacturing new machines to build the "new machines", and on and on. As Elon Musk found, "Making cars is hard". And my take is that high precision "humanoid robots" are decades away. Yes, yes, I hear the arguments flowing in: "But China!!" yeah, China is making humanoid robots that are "skilled" in running and jumping and dancing. In limited numbers, and certainly not useful in high precision manufacturing areas. Plus, they aren't washing machines. There has to be a market worldwide for these to be made "by the billions". Unless China gives them away, the 'average person' won't be able to afford them, and even then, I doubt they'll be capable of tending your garden and doing dishes. The amount of power they will consume is currently WAY PAST the usefulness criteria. They will have to be charged every few hours or sooner, depending upon the tasks. When battery technology comes around, then you'll see an uptick in practical uses. Until then? Billions of robots?, nope.
