I mean I would expect you to back up your claim with some kind of scientific study that humans in general opt to produce value for society purely altruistically.
I highly doubt that’s the case, but I have an open mind and I’d be delighted to be proven wrong.
As I understand it, most societal benefit and technological advancement has come from humans acting selfishly. You develop an idea while seeking profit — not necessarily money; this behaviour far predates money — and society benefits as a side effect (if the development of that idea is in some way beneficial).
