In college, he thought about what he wanted to do with his life, using as his starting point the question, “What will most affect the future of humanity?” The answer he came up with was a list of five things: “the internet; sustainable energy; space exploration, in particular the permanent extension of life beyond Earth; artificial intelligence; and reprogramming the human genetic code.”
He was iffy about how positive the impact of the latter two would be, and though he was optimistic about each of the first three, he never considered at the time that he’d ever be involved in space exploration. That left the internet and sustainable energy as his options.
Pretty sure the heftiest question on my mind in college was “How can I get away with doing the least amount of work for the most amount of reward?” and went shallower from there. Definitely keen to find out more.
