Partially. Telekom keeps up the line for months at a time. I guess that is due to telephony being done via VoIP, and they don't want to interrupt your late night calls.
Others, even Congstar (which is a cheap telekom brand), do 24h disconnects with a new v4 address, and no v6 at all.
The DSL I use gives me a fixed v4 and v6 range, but still needs to do the daily disconnects.
Our TV started to complain that the Wifi module was unplugged (which apparently is on the main board). Problem: This happened regularly with a dialog box. 'Solution': Put a Wifi dongle in the USB port.
From my vantage point, it is already. The only parties that don't have IPv6 are my employer (which I maybe need to nag about since we're an ISP and have our own AS), and the customer I'm dealing with.
Practically, my laptop is in some Wifi network and has an IPv6 address, but that isn't accessible from the outside because the Wifi/router box blocks incoming connection. That is a wise decision overall, but unforunately replaces the "can't connect because NAT" by "glorious IPv6, bit still can't connect".
Mobile carrier NAT, mobile device hotspot NAT, vmware NAT - that's the most I've seen so far.
But IPv6 in home networks replaces the unreachability-because-of-NAT by unreachability-because-of-filtering. The usual home router protects your clients, and if it's not your box, you're out of luck.
To think of it - I might have heard these two pass by. Not on that flight, but I lived with my parents in northern germany, not far from the danish border, and en route from the north to the baltic sea and on to russia. I often heard the badam, accompanied by a creak of the wooden roof.
Kleinwalsertag. Austrian territory, but only reachable (by road) through germany. Was connected to german phone network, which changed once telco stuff got smart enough. Effect: For some time a german and an austrian phone number reached the same phone.
I.e the 10% are not worthy of having an ISP, or health insurance.
As for the ISPs, this often isn't even about the customers being annoying, but simply their subscriber line being rotten or in an undocumented state which to sort out is too complicated for the tech-drones.
Definitely not 'expected'. I like the mailing list bug tracking more than having that on git{hub,lab,whatever}.
git makes it even possible to host a repo on multiple git* hostings, but apparently nobody came up with a successful distributed pullreq/issue tracker yet.
IHMO post-scarcity could have started long ago. The problem will be that the people out of a jobs can't think of something new to do, at least not as fast as the machines (or the people with the machines).
Subjugation already happens. When it's easier to keep the population poor and just raid the natural ressources of a country, that's the way it often goes.
It shifts the balance. Even if my hotline gets bombarded by mechanical turks the costs are the same on both sides.
Now google duplex can go and phone up every businessowner asking for the current store hours (or whatever), thus dumping the work of updating google's information on the store owners at essentially no own cost.
And the store owner does not even have a chance to find out whether it is a customer that will in some probability show up, or if he's just being used.
