No doubt. I am so grateful that on a construction jobsight I can pull up pdfs of appliances and lighting and materials orders and have questions answered immediately vs. having to wait a day or longer vs. the pre-internet days of simply not having access to that information in a timely manner at all. AR may be even more helpful.
Yeah, I think this is a technology that has real commercial applications. On the consumer side, of course there will be the games and porn, but there's real world value in having a heads up display always available on the commercial side.
Games will take time to develop beyond a novelty, professional applications will be niche and specialized but carry real economic value, porn will fund the technology development through the early adopter phase.
