By 2025 they might figure out newer processes than 14nm, but even Intel and Global Foundries has hit a wall at 14nm. Samsung, TSMC and IBM are the only companies with productive sub-14nm fabs.
Which is a fascinating lever from a global politics point of view. People theorize that the US might not come to Taiwan's aid, but how could we not? That fab seems too important a chess piece to surrender willingly.
IBM no longer has fabs. They sold theirs to GlobalFoundries a few years ago.
