I imagine a number of Hacker News members might be devs that haven't dealt with terms like “price discovery” before, so we should all try to show grace.
Even among college graduates, only 17% could correctly answer a basic econ question (pre-AI) [1].
I looked up one ~1,000 page econ textbook, and it does not seem to mention price "discovery", or at least the only uses of the word "discovery" were about things like a scientific/oil discovery [2].
"Even high-achieving students demonstrate relatively lower understanding of economics compared with other subjects." [1]
