I agree with the premise of this article. That armchair quarterbacking is rarely helpful and usually oversimplified. But I dislike the common implication in the headline, which is that intelligence somehow always equates to wealth. First of all, it's not always easy to judge how wealthy another person is, no matter their profession or outward appearance. Secondly, I think we all need to disuade ourselves of the notio…
Let's say you are a genius OCD person being elated by seeing the numbers on your bank accounts go up and nothing much else. You live 60-90 years and at the end you have some big number there. In this case you were successful.
Let's say you are a more typical person, you'll probably have a larger set of reward functions and they may even change over time. Having money on the account to be able to cover costs and do some vanity spending is definitely rewarding to a point - until it becomes hollow. But then there are all those other reward functions, like maintaining a family, seeing your kids grow up, see the world, play games, learn new things and maybe build or invent a thing or two. Maybe just shine as a social focal point or any number of other things. Maybe just watching turtles in various environments.
The only thing that we can't extend as a reward function is acquiring more time, like money on the bank account. So balancing the reward functions for a reasonable contentedness with life is generally what we strive to do, even if we don't spell it out that way.
We start young and see all the possibilities and the scarceness of time is not a pressing matter - reward functions are more about enjoying life. Then with a family you see time passing, become more aware of it. You learn from the things you messed up and know that some things can't be fixed and your reward function will become more about stability and preservation.
And then you die.
