Interesting that you think that, because I was actually fairly unimpressed with that comment. He leads of by saying the algorithms to do it have already been created without actually mentioning what algorithms he is talking about. He also claims that they somehow don't require that they run on trusted hardware which is pretty hard to believe (of course this assertion is completely unsupported in the rest of his comment).

The rest of his comment falls back to a fairly common computer security fallacy: We used it once and nothing terrible happened, so it is probably secure.
