I feel such pressure to use our new skills to solve these problems, but I know 10 years ago they were a combination of invisible/impossible to me. If I hadn't been aggressively pushed by smart feminists to examine my life more closely I might still feel the same way. If I hadnt been intellectually curious enough to stick with them, despite their worldview seeming so alien and wrong, I would probably be working in VR now instead of housing.
Maybe it's just that such challenges are too dark for some people... Mars is all optimism, no need to struggle with the realities of evil. Maybe some people just cant handle the pain of working on poverty and violence. I totally understand the desire to avoid fields where evil plays a daily role in your job. I grew up in an alcoholic household so pain seems sort of normal, although I have an intense desire to dismantle its causes. I accept that a more emotionally healthy person might just nope out of such challenges.
I guess it's also a little like the video games vs life choice: Mars is a clear goal, with all the players in a clear sandbox. Poverty is a messy mindfuck of a problem. That makes it more intellectually challenging, but also scarier. Failure hurts worse: a rocket that doesn't launch is one thing. Watching your friends die is another.
Still, it puzzles me that so many smart people need something like Mars to feel like they have a hard problem that's worth solving. I see so many around me. Easing violence seems like such a bigger win than getting off planet.
