Who's going to replace them in the foreseeable future?

Intel needs a massive cultural change to become a successful foundry and regain their moving to new nodes mojo. Samsung is too messed up to play this game at TSMC's level.

Nobody else it trying now, but that might change if TSMC is indeed being "greedy" vs. passing on their increasing costs. The article talks about the pressure of making new fabs but I can't help but notice inflation is roaring now.

I'm also given to understand greed is not part of TSMC's DNA, but that can of course change over time.
