"I think it is a mistake to hire huge numbers of people to get a complicated job done. Numbers will never compensate for talent in getting the right answer , will tend to slow down progress, and will make the task incredibly expensive."

“According to the geological records, earth has been around for around 4.5 billion years, although it was mostly molten magma for about half a billion years... The sun is gradually getting hotter and bigger, and over time, even in the absence of global warming — the man-made stuff — the sun will expand and it will overheat the earth. My guess is probably... there is only several hundred million years left.... Basically, if it took an extra 10% longer for conscious life to evolve on earth, it wouldn't evolve at all, because it would have been incinerated by the sun. ... It appears that consciousness is a very rare and precious thing, and we should take whatever steps we can to preserve the light of consciousness, and the window has been open; only now after four and a half billion years is that window open, that's a long time to wait ... I'm pretty optimistic by nature, but there's some chance that window will not be open for long, I think we should become a multi-planet civilization while that window is open, and if we do the I think probable outcome for Earth is even better, because then you know Mars could help Earth one day. And so I think we should really do our very best to become a multi-planet species and to extend consciousness beyond Earth, and we should do it now. Thank you.”

“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.”

“We will coup whoever we want! Deal with it.”

“If somebody wants to stay in their house, that’s great. They should be allowed to stay in their house, and they should not be compelled to leave. But to say that they cannot leave their house, and they will be arrested if they do, this is fascist. This is not democratic. This is not freedom.”

“The fundamental message that consumers should be taking today is that it's financially insane to buy anything other than a Tesla. It would be like owning a horse in three years. I mean, fine if you want to own a horse. But you should go into it with that expectation. If you buy a car that does not have the hardware for full self-driving, it is like buying a horse. And the only car that has the hardware for full self-driving is a Tesla.”

“So, I think the best analogy for rocket engineers, if you want to create complicated software, you can't run as an integrated whole, or run on the computer it's intended to run on, but, first time you run it, it has to run with no bugs. That's the essence of it. So ... we missed the mark there.”
