That should have started a couple of years ago. About a year ago I did
some IPv6 training for a customer. They just bought a very expensive
commercial cloud solution (BULLSHIT! I win.) with no IPv6 support.

That would be fine. Especially as I'm getting payed for IPv6
trainings. But you first have to realize that you need IPv6, than you
need the people how want to do IPv6. And you need the management who is
willing to pay for training ("We hired you to to your job. You don't
need any more training. If you want to do it on your own time and with
your own money").

Thats eays if you didn't skip 1 and 2.

Or v6 only.

Sure. But people out there don't see it this way. They still plan and
build IPv4 only. About 3 or 4 years ago I helped with setting up a large
network which was planned IPv6 only 2 or 3 years earlier. "IPv4 should
only be tunneled" was one of the thing written in the original concept. 
When I joined most of the admins couldn't spell IPv6 and everything was
IPv4 only.  One of the internal colleagues attended the Cisco CCNÜ
routing course at that time. They skipped IPv6 completely. Trainer: "You
only need IPv6 to get 100% in the test." :-(
