This is a big issue, there's a lot of bright young people doing the equivalent of cleaning oil off seabirds because they feel they gotta do something about environmental risk. On the other hand, theres a lot of greens arguing against nuclear power and for growing tomatoes in greenhouses to save on aviation fuel, so maybe there isn't enough brainpower being dedicated to the topic....

Anyway the flipside of marginal utility here is comparative advantage: what skills do you have that can help with AI research?
