Are we really not getting anywhere? (Serious question, not something I know much about.) Is there anywhere that significant progress is being made in IPv6 usage? If so, is it isolated to particular kinds/parts of networks?
Many of the largest content providers (Google, Facebook, Wikipedia, YouTube, Netflix, iTunes, CloudFlare, Limelight, Akamai, 40% of the US government) have deployed IPv6 in production. Many of the largest ISPs have as well (In the US: Comcast, Verizon, AT&T, T-Mobile, Google Fiber).
The problem is the last mile. User End. With Super Outdated Software and Router that dont support IPv6.
