>IPv6 has been around long enough that it's clearly a failed project

You have a very radical definition of "failed". Take your emotions out, and perhaps you would get a more objective evaluation of the technology.

For one, it's very clear that IPv6 has only, truly received global attention after the depletion of IPv4 address space -- someone has already linked the Google IPv6 adoption page, go have a look at it, look at the flat line before 2012. That means we have spent about of 10~15 years of time deploying IPv6, not 30 years, and getting to 50% adoption in such a time period is not what I'd describe as a failure.

Secondly, if you are defining failure as "less than 50% prevalence in 30 years" then HTTPS before 2014 will probably fall under the same category too. (Don't underestimate the age of SSL/TLS.)

Do you consider HTTPS a failure?
