Yeah, botched my numbers, sorry. I saw that the hash rate of the current Bitcoin network went up to 2^93 hashes per year, and then I managed to pretend 2^128/2^

Yeah, botched my numbers, sorry. I saw that the hash rate of the current Bitcoin network went up to 2^93 hashes per year, and then I managed to pretend 2^128/2^93 = 35, instead of 2^35. With your numbers if humanity dedicated all its energy to brute forcing a 128/bit key for a year it would have a ~0.1% chance of finding it. I guess that's a pretty good argument that no one is going to even try it in the foreseeable future.
