>The really sad thing about IPv6 is that it's a relic of a bygone era. The internet was envisioned as a thing where every device on every network could, in principle, initiate a connection to any other device on any other network. But then we started running out of addresses, ISP's wouldn't give you more than one for a household, so we started doing NAT, and that kind of sealed the internet's fate.

I thought the problem was lack of upload bandwidth for almost all households without fiber to the home. Surely, if people had symmetric broadband internet at home, then there would have been commercial solutions to allow devices to connect to each other, thereby decreasing the need for giant cloud providers.
