Sounds like there is a need for investment into innovation beyond just building the next-generation fab for $2^x billion. Bringing the cost of a new less-advanced fab down from $2 billion to $100 million, and then building 20 of them, could also be profitable (though less exciting). There is a national economy that's actually been growing quite well for a few decades now by applying that general idea to other industries.
