Disclaimer, I haven´t followed all the posts in this thread. However, the question is interesting. Whatever technology replaces domains will have to enter the realm of advertising and marketing. This is the superpower that domains dominate. Domains are not just part of technology. They are brands. And they are a layer of technology. Which means that they can sit on top of any new technology that replaces, say, current IP address system.
Addressable, direct-to-consumer, broadcast TV tech... that can actually turn-on your device to deliver a personalized, interactive (multimedia) message, based on your individual public and private (opt-in) data sets (including medical, household, consumer, financial, etc.) is the ultimate advertising and marketing superpower because TV is the ultimate advertising platform.
And, as NextGen TV is the first generation of broadcast TV with Internet Protocols baked-in it can now merge its new 'Precision Broadcasting' TV ad tech with the online video advertising market. This is like YouTube having a national network of affiliate TV stations, like CBS. Beyond that, NextGen TV broadcasts can also function as a premium (audio & video) quality streaming video platform, like HULU: ads optional.
The Problem with 'Domain Technology'
IP addresses are a name-node backbone with domain owner privacy cloaks. As a result, the ip addy 'ad platform' is the internet's main attack vector. From parked spam to ad-cloaked malware, IPhish-in-the-middle attacks, bot nets, and so on. Domains are cannibalizing the web at an increasing rate.
At present, the 'domain superpower' is being abused. While enormous value will remain in a few 'brainy' domain nodes -with dominant web platforms, and other domain names will retain some face value, the reality is... entering an escalating cyber-attack zone is a major deterrent for end-users. Existing players suffer major attacks and diminishing returns on the cyber front. Spending on cyber security increases by a double-digit percentage year-over-year, but there were twice as many cyber attacks last year than the year before -which had ~40% more than the year before it... so many are ready to change the channel.
As someone invested in both domains and NextGen TV, I think domain names do have an untapped superpower that could keep them from suffering the same fate as electronic text & graphic pages did when video networks took over Cable TV. But its early days. It'll take a few years to roll-out NextGen TV.
