> At Tailscale we believe the main reason for the slow IPv6 rollout is that it simply has not been able to provide enough direct value, when deployed as a hybrid in parallel with IPv4. The intention was to deploy IPv6, then retire IPv4 completely, in which case IPv6 would have made the Internet overall simpler and cheaper to manage, which is a big benefit. Unfortunately, this value doesn’t materialize until the very end, after IPv6 has been fully deployed to billions of devices. This means companies usually will not recoup the costs of IPv6 deployment on a predictable timeline, which makes investment hard.

Anyone else get a strong climate change parallel vibe from this section? Hopefully the stronger (dis)incentives of a slower rollout of carbon reduction efforts will be able to overcome some of these same obstacles.
