I think you're grossly underestimating the number of people here who fell into software development because it's one of the best outlets for "the knack" in existence. Sure, this site is split between the "tech-bro entrepreneur"-types and developers, and there are plenty of developers who got into this for the cash, but in my experience about a quarter of developers (so maybe 10-15% of users on this site) got into this profession due to getting into programming because it fed an innate need to tinker, and then after they spent a ton of time on it discovered that it was the best way to pay the bills available to them.
I got stupidly lucky that one of my hobbies as an avid indoorsman was not only valued by the private sector but also happened to pay well. This career was literally the only thing that saved me from a life of poverty.
