I'd agree with the top of Unman's comment about striving for more, while disagreeing with the bottom.
Signal is better than PGP.
Running crypto without PFS in this threat environment is an irresponsible bet to make with data.
My point was that failing to continue to maintain vigilance, even if it sounds paranoid, is also irresponsible. Unless one is willing to be that we have a perfect crypto system, some amount of humility (as evidenced by Moxie's speech) is warranted. Else we'll be talking about Signal in 20 years in the same way we're talking about PGP.
