We can expect a big Intel return by 2025.
By that day they will have, as firsts, the new ASML's TWINSCAN EXE:5200, they own a new state of the art fab, and they have full US government's political and coercion power at their back, it means they will be able to poach talent and get technical and trade info out of TSMC and Samsung freely.
I would not be surprised to even see Intel entering TSMC as shareholder, eventually sharing the ownership of TSMC new US fab.
After visiting TSMC in Taiwan, Intel CEO said he pursue a "long-standing relationship with TSMC", for US mentality it means they will buy it or enter as shareholder, they will not remain simple customers. Something similar to Western Digital and Toshiba, where the latter designs and produces memories and the former get the benefits and dictates the strategy.
...and if TSMC does not want to sell? Well...just make a phone call to Washington and everything will be fixed. Taiwan is too small and to dependent on US to have a say. And it seems they bound themselves to US more and more every day. It seems impossible to me that Taiwan people miss the simple reality that, when you are bounded to US big brother, US will ask you to do something and you will not be able to say no. Even for entire continents like Europe, is
very hard to say no to US.
