My experience with researchers (though not in AI) is that it's a bunch of very opinionated nerds who are mostly motivated by loving a subject. My experience is that most people who think really deeply and care about what they do also care more that their work is prosocial.
> care more that their work is prosocial
These takes are always so funny to me. The whole reason we even have the internet is because the US government needed a way for parties to be able to communicate in the event of nuclear fallout. The benefits that a technology provides is almost always secondary to their applications in warfare. Researchers can claim to care that their work is pro-social, and they may genuinely believe it; but let's not kid ourselves that that is actually the case. The development of technology is simply due to the reality of nations being in a constant arms race against one another.
Even funnier is that researchers (people who are supposed to be really smart) either ignore or are blissfully unaware of this fact. When you take that into consideration, the pro-social argument falls on its face, and you're left with the reality that they do this to satiate their ego.
