I don't know how Intel operates. Did they start building a 90nm factory before they finalised the process of making a 90nm chip? Can they upgrade a 90nm plant to start producing 45nm, and will it cost less than half of the original spend? As for pharmaceuticals - I'd expect their plants to a) be capable of producing multiple different compounds and b) equipment to be modular. Research & clinical trials are expensive, reconfiguring equipment to make newly discovered drug is cheap. Once proven to work, drug can be replicated fairly quickly and cheaply, that's why they push so hard against any patent law reform.
