There is a subtle danger in a man thinking that he is "fixed" for life. It indicates that the next jolt of the wheel of progress is going to fling him off.

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.

There's a tremendous bias against taking risks. Everyone is trying to optimize their ass-covering.

This truth may be unfashionable, unpalatable, no doubt unpopular, but, if it is the truth, the story of mankind shows that war was universal and unceasing for millions of years before armaments were invented or armies organized. Indeed, the lucid intervals of peace and order only occurred in human history after armaments in the hands of strong governments have come into being, and civilization in every age has been nursed only in cradles guarded by superior weapons and superior discipline.

If you're not concerned about AI safety, you should be. Vastly more risk than North Korea.

If you punish people too much for failure, then they will respond accordingly and the innovation you will get will be very incrementalist. Nobody's going to try anything bold for fear of getting fired or punished in some way. The risk/reward must be balanced, in favor of making bold moves.
