The tech was not ready for consumer glass yet going the business root will keep it alive. in 5 years it has a better camera processor and larger battery. Now I expect it to permeate into a consumer product organically in the next 10 years as the tech keeps improving and it is adopted for other stuff. I would love to have something like this while watching sports in the stadium where I could see live stats. With 5G internet, machine learning/AI it is something that will be possible. Something that you see as the view of a robot in movies like terminator. By then most of the 20-25 year olds will be the facebook generation who have been monitored all their lives in different ways and wont have the same privacy concerns.
