I think it was always intended to be sort of a joke. "Interesting" is subjective, but obviously any self-consistent criteria of interesting cannot allow something to be interesting by it's sheer uninterstingness. But even if you're willing to accept the paradox, it's still a bullshit proof. It's one thing to say a number is interesting because it really is the first number you can't think of anything interesting to say about it. It's something else to say to say it's interesting because its the first number you can't find anything interesting about, not counting all the others that were considered "interesting" for the same reason.
