Good excerpt below on interplanetary travel:

FC: What do you think of Jeff Bezos and Elon Musk pursuing interplanetary travel and Mars and moon colonies because they don’t seem to believe that we can save our home planet?

YC: [Laughs] I think it’s pretty silly. And not just silly, but it’s really a shame. The monies that are going to space exploration should be used to save our own planet right now. We’re in a triage situation. Things are so grim. It’s World War III. I lived through World War II, and I remember what the country had to do to mobilize. You couldn’t buy sugar. You couldn’t buy meat.
