Yeah, it's always the same with IPv6 discussions. The main points being:

  1. IPv6 addresses are too long to remember
  2. IPv6 doesn't need NAT and people are uncomfortable with their devices having a public address as they see NAT as an additional layer of security

I dismiss IPv6 because my ISP doesn't support it.

That's because the Internet is basically broadcast TV 2.0 so no one cares about having public IPv4's at home as long as they can get to their memes and streaming. Great job, we took something that was meant to be a next frontier in humanity and let anyone connect with anyone else without gatekeepers/intermediaries and turned it 21st century brainrot troughs. Perhaps a society not in slow intellectual decline would have chosen otherwise.
