[Question] what exactly is hard about adopting IPv6?? (programming.dev)

I mean on a technical level. Are the devices that make up the infrastructure of the internet hardwired with IPv4? Is the firmware on these devices impossible to upgrade remotely?

If it's just a matter of software or firmware then adoption should only take like a year but clearly that isn't the case. So what specifically is stopping us?

Simply there's no value for an individual/company to put in the effort.

I have zero need for IP6 in my home network, my company has zero need for it internally.

Honestly, IP6 is useful only for internet backbone at the moment. So long as a packet can reach an edge router/gateway, IP4 is fine internally (because that infrastructure is already in place, and transitioning is costly and has risk).
