There is an implied collectivism in your statements. The idea that "we choose to reward people who are successful" implies there is a collective with the legitimate authority to make such determinations. I reject this idea. Instead I propose that legitimate authority only exists to create a liberal ecosystem, not to meddle in the outcomes that ecosystem produces. A person's fortune (or misfortune) to be born with particular traits, into a particular childhood environment, is entirely their own. I see no source of legitimacy to redistribute that fortune to other people without explicit consent.

It does not require believing in determinism to believe a majority of one's outcome is based on context that they do not control. For myself, I didn't choose which country I was born in (I happen to be born in a wealthy country). I also was not born into abusive parents but rather parents who valued science and school. We happened to get a computer early because of my dad's job and I happen to have enjoyed it. That doesn't mean it's a deterministic outcome, but it is chaotic, in the sense that given all these inputs it's not possible to predict the outcome. And small perturbations can have significantly different outputs.

> "Luck" is just a dumb concept we humans use to handwave away edge cases.

Or maybe this view is just people who really want to believe there is something else. What is that something else?
