alt Hacker News> Future proofing it by jumping straight to 128 bits instead of 64.
It's hard to disagree with your point since 64 would definitely have been better than the 32 we have. I'm not convinced the choice of going for 128 bits posed any real challenge to adoption though.
The irony that I forgot to voice is that if we had gone 64 and feeder features we’d be farther along in adoption now and probably be consuming the address space at least a fraction as fast as people feared.
By raising the barrier to entry so high we guaranteed the features would likely never be needed.
