Elon Musk:

"When I was kind of growing up, I did have this existential crisis where I was like, what's the meaning of life? Is this all pointless? Is there any point in existing at all?"

"I read the various religious texts and I read a bunch of the philosophers and I just couldn't really seem to find any good answers and then I read Hitchhiker's Guide to the Galaxy which is really a book on philosophy but it's disguised as a book on humor."

"The point Douglas Adams was making is that the purpose of life is to learn more, to ultimately know what questions, to learn what questions to ask about the answer that is the universe. He was sort of making that, like that's the actual point, is to figure out the point."

"And so therefore we should take the set of actions that are likely to expand consciousness and our understanding of the universe so that we can know what the meaning of life is or why we're here and how the universe came to be."
