AR is essentially in beta. There are no consumer-oriented products and the improvements between generations are huge. Much, much too early to say it has failed.
There are plenty of consumer-oriented products if you count the average phone. iOS and Android have both made big plays around AR. While it's not "goggles AR", it's also seeing a slow but steady adoption by consumers in the boring, but still important to AR handheld way.
You'll see people randomly using the measurement tools and other "boring" AR utilities all the time now, and then there are games like Ingress, Pokémon Go, and the soon to be released Harry Potter AR game, which all have rather large consumer adoption.
AR is getting so prevalent it's already "boring" or just a part of the user experience for consumers. What that means for eventual adoption of "goggles AR" for consumers is an interesting question. It's probably going to come down to form factor preferences and how many people want their main computing device to be in their pocket versus worn on their head, or how easy it is for the device to "flex" between roles as interest/necessary.
