I responded on the assumption that the original poster was saying Musk intended counteracting an existential risk to be an audacious goal, a visionary moon shot, rather than just a "net contribution". By that measure, he's not succeeded. In any case, he's not been as successful at solving climate change as he has been at increasing his personal fortune.
There are a lot of shades between saving the world and evil.
My position is that Musk has focused largely on business that can or do make the world better, and also make a profit. The two are not mutually exclusive and I think the former is a major factor in what Musk selects. Obviously good is determined from Musk's perspective,but I have generally agreed with him with respect to Tesla, spacex, boring, neurolink, solar endeavors, and xprizes.
I don't believe that those
up thread were actually claiming Musk will or thinks any of his ventures single handedly will solve climate change. If that was your assumption, I think it was wrong.
I am curious if you agree that his work in these areas is laudable?
I agree that it seems like he is more successful at increasing his fortune than solving the world's problems. I don't hold that against him because the latter is a very tough challenge. I don't hold the fortune against him because it was made from companies that advance humanity, and most of it is tied up in other ventures that also advance humanity. I don't know about the whole Twitter thing, which could be a deviation from this, but I am open to the idea that it could be an improvement over the current state, if not particularly relevant to humanity. I am also open to the idea that he thinks it is more relevant than I do.
