That's exactly right. Bad leadership got them here. Of course they won't suffer, but their employees will. But only because they announced it as AI related. So the investors don't care.

You missed the point and almost every counterpoint in your list is wrong.
>> - link local gateway address, makes it hard to understand why the subnet does not have a gateway from the ssme address space
>IPv4 has link-local addresses, too. Those are the 169.254.X.X addresses that you see on Windows machines. IPv6 adds nothing new.
That's not what the OP said. Note it says gateways. IPv4 when DHCP'd will show 192.168.1.1 for example when it has a 192.168.1.55 address. IPv6 will show fe23::166:8f2c:9a21:96de when it has a 2001:921:61c:aef:78f:7190:1ca2 address, despite the gateway actually being 2001:921:61c:aef::1. So its highly confusing for no good reason.
>> - privacy extensions: it is very hard to explain to people why they have 3-4 IPv6 addresses assigned to their computer
> Well then, don’t use them. Configure the machines with one address each, just like before. If you want the (arguable) advantages of the privacy extensions, they are available, but not mandatory.
While you can configure not use them, by default DHCP'd devices WILL have a bunch. Again confusing for no good reason.

It's the complete opposite experience for most people, including network engineers.
For me, the journey is more important than the destination. Using coding assistance takes all the fun out of it, as well as the learning. (Not to mention adding aggravation of dealing with prompts and figuring out whether the response is correct or not).
