The ones who care about AI research and developing software for that kinda stuff, should do that. The ones who can contribute to medicine, various engineering disciplines, or anything else that benefits humanity should do that too. The ones who'd rather squander their lives away when good things that'd benefit others are within reach (regardless of which discipline that is in, AI being just one of many)... I mean sure they can do that but maybe shouldn't do that.
I don't think the readings of anything I've said here are at all charitable so I'm done engaging in this discussion.
