Most consumer networks are IPv6 by default. Most cellular networks are IPv6-only/IPv6-native today with big DNS64/NAT64 gateways to the IPv4 web. Most consumers don't know or care, they just use IPv6, daily.
A lot of the holdouts on IPv4-only traffic are corporate traffic. A lot of corporate traffic acts like it wants a separate internet anyway, and a lot of companies hoarded IPv4 spaces for long enough that they don't see the increasing costs of IPv4 addresses hit their bottom lines yet enough to care. It's a fascinating dynamic. Maybe corporations will just buy the remaining IPv4 internet entirely and keep it as their own separate but not equal network.
