I’m not really understanding the notion that these people are so sincere. Perhaps we have different definitions of sincerity. To my eye, the entire fascination of unsafely injecting peptides in a desire to change your being is largely the opposite of sincerity.
Yeah, isn't the entire point of SF startup culture (for the last decade++) to build personal wealth through a successful exit rather than build a sustainable business that benefits society? It's a big speculative con game... Opposite of sincere. Of course we can warp the semantics and argue that these people are "sincere" in their desire to defraud retail investors or something, but that doesn't seem to be the author…
But there are lots of people with a sincere mission who we don't hear about, because they're quietly working toward their goals.
That doesn't say that their goals are worthwhile or that what they're doing is actually good for the world, but they can still sincerely believe it is.
Most of them fail, and we hear about precious few of them. That doesn't make them any less sincere either.
