I thought it was tokens
Would have thought advertising and transaction fees myself, but the article says it's usually oil (ok I should have thought of that), "pharmaceuticals" (mkay, seems cheaper to make elsewhere so that's a bit strange), or aircraft and their parts (wut? How many aircraft can the world need that it commonly tops the export chart of the wealthiest country?!)
I mean, wouldn't that make sense given the market caps?
So many trillion-dollar valued AI-focused companies.
I think those count as services. Gold is the most-exported good.
