C'mon. You know it is not unresoved at all. For sure it is not on Hilbert's list of the unresolved Millenium problems
In any case, the fact that we do not agree, entails logically that at least one of us does not have God's knowledge within. Assuming that God knows the answer.
I definitely understand it is unresolved, but again, like other things there is an easy answer that suffices.
The fact we disagree doesn't entail that, as God's knowledge or actual knowledge is unconcerned with how illusions may be resolved. It's not like .999... actually exists.
