The line of primes is of the Peano kind:
# Linearly ordered, and discretely so
# having a minimum point, and
# having no maximum point
Thereby, it is order-isomorphic to the line of finite cardinals.

So, are you asking, in essence, for an upper bound to whatever cardinal
numbers mankind (or Sam) can "discover?" Or is it conceivable that a
particular algorithm through which the mind ... or other machine ...
identifies primes has its own limitations ... perhaps because of limitations
of the respective "machines"?
