To be fair, if I was a billionaire and I had the choice of helping ordinary people or doing something awesome, I would definitely pick to do something awesome. I respect Bill Gates for fighting malaria, but I would go for spaceships or robots.
Gates has the money to do both, and more. It’s just sometimes better to let others do it instead— having your own space company means worrying about competition, contracts, and potential profitability. Meanwhile if he wanted, he could hitch a ride on any of their rockets with no effort.
Musk and Bezos also have the money to do both, but they merely elect not to. Perhaps in the future they will, like Gates, begin funneling more of their effort and wealth into altruism to improve their reputations.
I'm an engineer, so my childhood fantasy wasn't to ride on a rocket, it was to invent a rocket. I did think it would be cool to explore space, but not as a test pilot or a tourist. To be honest, I don't think I'd go on one of those tourist flights even if it was free - I feel no urge to risk my life just to get a good view of Earth. Being a space colonist would be a different matter - then I'd get to actually use my skills to build stuff.
(The reason I think this is relevant is that a lot of these tech billionaires were originally engineers too, so I guess they also think like this.)
But if it's something awesome marketed towards saving humanity then do something actually awesome and impactful instead of distracting bullshit like hyperloops and Mars colonies on unrealistic time-frames and self-driving cars instead of public transportation. Endless talk and grand gestures when these people have the resources to really drive improvements/innovations in achievable realistic projects.
Lol it's not virtue signaling it's malicious compliance. My workplace has vacation and sick days pull from the same incredibly small pool. They're also very anti work from home. So since I've explained the problem and was told to just take vacation time when I'm sick, I decided to just not "be sick" and explain the problem when it comes up next
