What exactly are you trying to imply with this quote? It seems like you're suggesting that Schneier's quote may become infamous one day should 256-bit key cryptography become crackable, which it might, but you say nothing as to how Schneier's argument could ever be wrong. He is saying that thermodynamically speaking, brute-forcing 256-bit key symmetric cryptography is unlikely to ever be possible. Do you think that to be false?
