It's not DoA, the tech has been in production for close to 15 years. If you've been to Disneyland you've heard audio broadcast over IP, or watched a match of League of Legends (or virtually anything that comes out of a stadium). Hell if conventions were still around, go to NAB or AES and look for the "we speak Dante" signs everywhere.

The problem AES67 solves is that there are multiple competing standards and it's difficult or impossible to connect them over the same network. The standard is there to unify under one protocol. The tech problem was delivering audio in sync over large networks, and rather than use custom hardware they used commodity networking gear and network protocols (not doing that might seem crazy, but that's generally what happens in high end audio). But even then, you probably have some special hardware in your environment to connect microphones and speakers to the network in the first place.
