On a more serious node: IPv6 can be short and if used right they are actually short. Unfortunately, people continue not to care about relearning their habits and treat IPv6 as if it‘s a 1:1 replacement of IPv4 (you can even see it in this threat when people ask „why would you need more than a /64“). A major blocker in IPv6 aren‘t just the IPs but that all sys admins out there are trained to treat IPs as they got used to from the v4 world and can‘t stop to think of them as scarce resources instead of applying a hierarchical approach.
