This is a recent TED interview of Elon Musk, an amazing and inspirational man.
During the interview he says “People are mistaken when they think that technology just automatically improves. It does not automatically improve. It only improves if a lot of people work very hard to make it better, and actually it will, I think, by itself degrade, actually. You look at great civilizations like Ancient Egypt, and they were able to make the pyramids, and they forgot how to do that. And then the Romans, they built these incredible aqueducts. They forgot how to do it.”
So what he said is: If you’re not progressing, you’re regressing; so, keep moving forward.
It is fascinating to watch him thinking as he answers various questions. His observation about the future, at the end of the interview, actually choked me up.
