[Cryptography] More magical encryption thinking from James Comey

[John Levine]

In article <EC40AC0F-BBAF-40BC-BE92-42F5CF48ED4B at lrw.com> you write:

Comey is right (for once) about why slippery slopes aren't persuasive.

But crypto doesn't have a slippery slope, only a slippery cliff.  You
can't make secure crypto a little less secure, only a lot less secure.

The magical thinking is basically the assertion that there's a slope.
