Not stuck, but hardly a runaway success. That graph shows adoption at 40% and increasing, roughly linearly, at maybe 5% a year. At this rate, it's going to be 2040-2050 before we are in any realistic position for an IPv4 switchoff.
So: IPv4 space already pushing $50/address, ~$1bn of unused-but-potentially-routable IPv4 space (240/4) just sitting there, and 25 years to go before it becomes worthless. Any guesses what happens next?
