I think its more of a matter of perception than anything. IPv6 adoption has gone pretty smoothly imho, there hasn't been any major blowbacks or anything; for example the Google IPv6 adoption chart trend is steadily increasing.

Another thing you can see from Google IPv6 charts that before 2011 IPv6 adoption was near zero. This matches pretty well with IPv4 exhaustion; IANA pool was exhausted in 2011, and APNIC followed later that year. Before that anyone could get IPv4 address pretty liberally, so there was very little reason to think about IPv6. Especially in western world (RIPE/ARIN) where consumption was slower than e.g. APNIC; notably ARIN reached exhaustion only in 2015.

In summary, I feel that having third of internet become ipv6 in about a decade seems pretty decent result, considering how complex and especially diverse internet is.

Someone pointed out recently on NANOG the thing that probably killed a TON of IPv6 momentum was when they missed the deadline to get it included in Windows 95. Approximately no one was on the internet before then.

(Yes yes you nerds were, but most people weren't)

Seems pretty far fetched to me that there would have ever been a chance to have IPv6 in Win9x. For comparison, afain FreeBSD was the forerunner with IPv6 support, and they got it in 2000. So I'd say they "missed the deadline" by 5+ years. It was probably around 2005 when we realistically had somewhat usable IPv6 support at base OS level.

I think the point was that it changed the whole demand curve. If the major consumer OS at the time had v6 support things like FreeBSD would have added it earlier.
