It's important to learn math not because you may need to do long division as an adult, but because it promotes rigorous thinking. IMO, history and causal inference are among the most important subjects a young person can study — math being central to the second.
A significant problem in public discourse right now is people's inability to critically evaluate causal claims (e.g., vaccines cause autism, deporting immigrants will solve the housing crisis, etc.). The less able people are to critically evaluate causal claims, the worse our democracy functions because people can be preyed upon for votes. You should promote anything that improves rigorous thinking, even if it doesn't have market value. In fact, we should stop thinking of education only in the context of what improves the economy.
IMO, this is distinct from knowing your own address (which Huang can avoid because he's wealthy). Memorizing facts like this may or may not be important, but it's distinct from rigorous thinking.
Talking to an older parent about their health always feels kinda odd despite being a nurse. Also reminds me my delivery communication wise is kinda shit ngl
