It's not that bad - Samsung and Intel are at most 1-2 years behind TSMC. An eternity in terms of product cycles for sure, but society would not fall apart if Apple had to redesign their A15 and M2 chips for Samsung 5nm next year.
Everyone also seems to forget that every time AMD has caught up to Intel in the past either AMD has itself stumbled and/or Intel again jumped forward.
Intel's 7nm process (which is equivalent of TSMC's 5nm, which just began production work) has recently been delayed into 2022[1]

At least that’s the word on the street.
That's had a bunch of issues and is only now producing their premium mobile CPUs.
The 7nm issues aren't great but if it weren't for the 10nm disaster they aren't really more than normal slippage at this point. If it keeps slipping then they have problems.
