As a tech nerd who self hosts stuff, I'm more like "what is IPV6 and why is it causing me issues, I can't figure this out, I guess I'll disable it, wow my problems are fixed now."
I guess I can see why people don't like it, as it's caused me issues, but just because I don't understand it doesn't mean it's dumb. I'd need to understand how it works before I could say anything about it, positive or negative. I guess all I could say is that it's been way less intuitive to me, I can't memorize the numbers, and the reason it exists makes sense. Beyond that, I unno.
I should probably spend the time to learn about it, but I already have a full time job where I work on computers all day, I'd rather focus on my other hobbies while I'm at home.
It's not terribly difficult to learn when you avoid trying to relate it to IPv4 concepts. Particularly: forget about LAN addresses and NAT, and instead think about a large block of public addresses being subdivided between local devices.
Thinking about all my devices being exposed like that gives me the heebie jeebies. One public facing address hiding everything else on a private network is much less frightening to my monkey brain.
This is what a firewall is for. Blocks inbound to the whole subnet space. Better than a NAT, which can open a port through STUN or simply a malformed packet.
Back in the days I had an ISP that offered me IPv6 network, it was really easy to self host things over the internet, because IPv6 is unique to all devices, so the server had its own IPv6 global address, which I could access from anywhere with IPv6 connectivity. No more dealing with port forwarding (considering that the ISP didn't block the forwarding of ports). Just a firewall setting and voila, the service was accessible. It's that simple.
