alt Hacker News> But the most unrealistic part of this story is how all the IoT automation continues to work in the absence of the Internet.
It's actually one way this story about the apocalypse is more hopeful than the present day. We don't need the internet to make most of the things in that story work, but in our timeline we'd add it anyway to get and sell those good analytics.
Except that isn't really why it happened: iot being Internet tied is because it's much, much easier to get devices to work when you control at least one side of the server with skilled professionals rather then your average home user.
And no one has really come up with an alternative: home assistant is good, but it's not for the non-techy.
I will squarely blame IPv4 for some of this: NAT has meant that the key application people might want to use is broken by default (remote device access) without mediation servers.
