"EDIT: I cannot stop thinking about how ubiquitous YOLO as a philosophy has become in the last decade. Everything about life has become a binary of win or lose. Your stock market plays "won" if you are in the green, your tweet "lost" if you did not get effective engagement, your latest commit "won" if the established metrics succeeded after deployment. And then there are the implications in machine learning, where everything becomes a binary "correct or incorrect" assessment..."

Much of this is reinforced through perceived and real rampant income inequality. If people think they can't advance without taking disproportionate risks - and they're mostly correct here - you'll start to see that action, and then it gets amplified in the social media atmosphere that we live in today.
