> Because if I was lucky enough to stumble upon some great hack to make lots of money, why would I be telling people about it? People like explaining things to other people. They like sharing knowledge, they like having other people pay attention to and listen to the knowledge they share. I am pretty convinced that it's an evolutionary adaptation that we feel a compulsion to explain and share interesting things we've learned. Your logic probably overcomes this built-in tendency for sharing things when the alpha is very directly tied to one's success. So, for example, a hedge fund manager isn't sharing their trading strategies. But if an executive is explaining how OKRs worked for them, or an engineer is saying typescript was a big help, our first instinct shouldn't be to assume it's a psyop. Those things are not the singular competitive advantage of a company, success is usually the aggregate result of many different things.
