> It has barely hit 50% and it's already plateauing. This adoption rate is ridiculous despite basically all network interfaces supporting it

It's fine. IPv4 and IPv6 can be used at the same time. There's no hurry. Network interfaces support anything as long as both sides agree (nothing stopping you from building your own IPX network over MPLS).

People can move to IPv6 when the IPv4-as-real-estate speculators get out of control, and if IPv6 prevents IPv4 rental prices from going haywire, then it's served a useful purpose.

I saw a news article that said something about India considering moving to IPv6-only? That's going to be interesting if the rest of the world moves to IPv6 and the U.S. doesn't.
