Ditching Ethernet broadcast that hit every single interface on a network when you only wanted to communicate with a single device on a specific protocol is a big win. Getting rid of Subnets by making the smallest possible subnet infinitely large eliminated 90% of network confusion around subnets. Privacy based IP addresses also a nice addition. After working with IPv6 for 10 or so years, you really grew to appreciate what an architectural advantage it has over IPv4. As for deploying it? I dunno - I just plug my Ubuntu laptop into a WiFi Network and it just seems to work. I'm pretty sure the comcast routers I've connected to have had zero configuration beyond what they can pick up connecting to comcast. In the future - people (other than say Network Engineers working for IT) probably won't even discuss things like "IP" addresses.
