It is also important to point out, the achievement here is how fast TSMC manage to set things up and running even without the home ground advantage. Intel couldn't even replicate this time frame if it was their Intel 7nm Fab. And of course the greatest record was that with enough planning and permission done before hand TSMC manage to have the fab built and running within 18 months in Taiwan. ( Arguably closer to 12 months )
This also means unless a miracle happen or US Gov being unfair with certain things the chances of Intel catching up with its current team, management, board members and investors, against TSMC in terms of capacity, price, and lead time as a foundry is close to zero. ( I am sorry but I lost all faith and hope now Pat Gelsinger is out. )
Once TSMC 2nm hits the ground later this year, TSMC US will also start their 3nm work if they haven't started now.
