Seems more like billionaires spending money on trying to live forever has an edgy image in non-billionaire cycles. Sure, maybe Gates and Buffet really aren't that interested in living forever, but the likes of Thiel and Musk aren't exactly noted for techno-pessimism or caring whether the average normie thinks they and some of their investments are creepy, and they absolutely have the dealflow and the connections to evaluate any promising life extension ideas. If they're still spending more on stuff like 140 characters, maybe the low hanging fruit just aren't that low
Thiel put a couple of million in some edgy stuff with little to show for. It is nothing compared to the order of magnitude that Gates invested in malaria.
Well yeah, that's my point. He's the exact opposite of the scenario you suggest, someone who's so committed to promoting the idea of life extension he'll chuck a couple of million at woo merchants in the space purely for signalling purposes, someone who go on podcasts talking about the compatibility of "ending death" with Christianity and has a personal life extension regime, but when it comes down to actually putting significant capital down towards near term life extension, he doesn't see the opportunity. It's not because he doesn't want to look edgy, it's because he doesn't believe what he's being pitched is going to deliver on useful timelines.
