   That makes sense. I’ve long thought that one’s estimates of the   
   probabilities of various events depends very much on one’s point of view.   
      
   I think Bayes’ Theorem says as much.

   None of our cryptosystems are provably secure. RSA depends on the assumed   
   difficulty of two problems: factorizing large integers, and computing   
   discrete logarithms, and would break if either one was solved. There is no   
   proof that either of these problems is actually hard: we simply don’t know   
   of any good algorithms for them, after decades, even centuries of looking.
