Stupid greed is taking so much as to starve your supply. Smart greed is sustainable greed. Smartest greed is one that feeds back into the supply, making it grow exponentially.

But isn't this just hindsight tautology? How would you know ahead of time how much greed is too much?

For example, I've been predicting the financial demise of Facebook for over a decade now (amongst other things for being too greedy), but Zuck's still doing well enough. Even if Meta is declining now, it still might have been rational for him to be so greedy over the past decade.
