Some claim tsmc is decade ahead, other say it is 3 to 5 years, etc, etc.
From my understanding both are in a race that will be decided in next 10-14 months and when it comes to the future, Intel has priority on next gen EUV (HighNA), so there is a chance
Various medias report that Intel has 1-2 year advantage due on tech like PowerVia
So, it is not that clear how far ahead TSMC is

Yes, they arent, so arent their customers who want geo diversified supply chain and risk amortization (Earthquake? War? Drought?)
Also they will have leverage when negotiating deals with TSMC
