All numbers are interesting. The proof is by contradiction.

Assume we have found an uninteresting number. If it is not the first uninteresting number, we can find earlier uninteresting numbers until we have found the first one. But then this number becomes interesting because it is the first uninteresting number which is a characteristic no other number has.

Thus we have arrived at a contradiction and there can be no uninteresting numbers.
