That's if you've already done the R&D work to design the nodes you're fabbing. R&D on new nodes can take the better part of a decade, if you're starting from scratch, and that assumes a fully-staffed R&D organization with all the necessary expertise already in place.
They could probably cut that time by a lot, if they can license most of the IP needed. However, I seriously doubt anyone is both able & willing to license them the IP for the kinds of cutting edge nodes he needs. IMO, they're thinking AI can makeup the difference, here.
