Feb 9, 2023 at 0:29 comment added Jeppe Stig Nielsen I have not checked the reference, but it seems that it follows that there are infinitely many non-Wieferich primes. Namely, for each $p\ge 11$, pick a prime factor $q_p$ from the squarefree part of $2^p-1$. The primes so picked are distinct and non-Wieferich. So is the question on the number of non-Wieferich primes settled?
