Google apparently hasn't googled why Google Glass failed

“We made one great decision and one not so great decision about Google Glass,” Teller said. The great decision was Google's Glass Explorer program, which invited a few thousand real world beta testers to wear Glass and provide every kind of feedback imaginable. “I'm really grateful for all of those Glass pioneers.”

“The thing that we did not do well, that was closer to a failure, is that we allowed and sometimes encouraged too much attention to the program.” Teller notes that battery life was a major challenge as was “[figuring] out how new social norms could be built.”

Yep, that was the problem, drawing too much attention to the program that features a horribly designed wearable that sits on your face.
