It takes years to build a new fab. The market has no patience for that. Intel is the cheapest tech company by a huge margin if look at book value. Those fabs are expensive, but even if nobody wants Intel processors anymore, they could even manufacture Ryzen's. The downside is that it takes 3-5 years to make profit on a fab, it's easier to be NVidia in that sense, but I wonder if it's sustainable in the long run.
