If the method stands up and considered fine, that means the shortest string is increasing at a rate of ~1 bit every 3 years.
That implies that if the Internet does not grow any more, we should be confident of a > 50% chance of a UUID not being universally unique in about 150 years.
Is this the next Y2K/2038 problem? :)
- C4stor 9y agoIf the traffic doesn't go up significanly, the shortest string increase will drop exponentially. Even with only the last 5 years, you can observe it's slowing down, and that's with an hefty amount of traffic increase to back it up. 128 bits is super safe for a long long time !
