Mostly agree. Audiobooks are not my thing, but of it were - I’d look for a way to resume where I left off, maybe some recommendation on what to listen to next.

In general - once you’re into hosting stuff and past the initial barrier of setting everything up - adding another service is dead simple.

It’s not v6 itself, it’s rather lack of layers of nat that prevent forwarding a v4 for most folks.

It doesn’t fix it, per se, rather removes the need for layers of hacks such as nat and cg-nat. Every device gets a globally routable IP - no need to forward anything, just open the port you want.

IPv6. My stupid ISP actually shipped their router with all inbound ipv6 blocked with no way to unblock it, so I set up opnsense. Works like a charm!
