Really? I think if we were to bring back our close ancestors (4-5 generations away) they'd look at our world like we see Harry Potter's: pure magic. I mean flying metal birds, fire that instantly turns on and off, machine that move around like ghosts, small boxes that can talk back, musicians on demand in a box? I think you get my point, you're selling humanity short. There's no limit to human ingenuity and there's a reason Elon Musk still doubts we're living in a simulation.
