Someone on HN once quoted some expert estimating that China could conquer Taiwan in two weeks. Surely a 100% reliable quote of a 100% precise estimate. Assuming that the invasion costs as much per day as the Russians spent per day in the first month of invading Ukraine, which has been 100% precisely estimated at $20B/day, the cost of seizing TSMC would then be $280B, slightly over half of its current market capitalisation.
It must be some sort of joke. Maybe a competition to see who can get the most ridiculous proposal past a conference program committee.
