I doubt it nets positive or even cancels out the damage, but if we're taking a fuller picture, then we shouldn't also assume Altman / other AI company CEOs are "taking actions to harm the world in grievous ways" for shits and giggles, or for large payday. Despite what skimming HN would make one believe, AI tools are actually useful in science, technology, and all kinds of productive work.
So the silver lining is this - they're not risking to burn the world down for porn or bitcoin, but for general improvement in everything across the board, that happens to have an unfortunate side effect of destroying value of labor.
I don't think that Altman is a Dr. Evil level villain who just wants to hurt people. I instead think that he does not care about the damage he causes on his path to personal wealth and glory and I think that this is precisely as terrifying. I'm sure that the machines made of my corpse would be used for productive purposes too.
Altman probably won't torture my cats to death. What a guy.
