We did, sort of. We have way more devices than ipv4 addresses, but a lot of them are using the same address and hiding behind a local network. For most broadband setups, your entire WiFi network is only consuming one public IP and it’s using a whole bunch of local IPs behind your router.
This bought us some time. Ipv6 was invented to make sure this “never” happens again, it has a far (far far far) larger number of addresses.
