Um ... Suppose A has a short simple proof using the Riemann hypothesis, and a short simple proof not using the Riemann hypothesis.  If the Riemann hypothesis is hard to be (as appears to be the case), then wouldn't the short simple proof of A not using the Riemann hypothesis make the proof of A accessible to those who haven't worked through the proof of the Riemann hypothesis?   And might it not be important for that reason?  17:14, 8 Sep 2004 (UTC)
