I think this does a good job of speaking to one issue with Glass. "It looks dorky" will fade. There are negative reactions for other reasons, but conflating all negative attributes of Glass isn't a good analysis.

For those raising privacy concerns as an issue with this analysis - do you think the "that looks dorky" reaction is in fact significantly motivated by privacy concerns, or can you imagine a hip-and-chic styled product that is nonetheless equally (potentially) voyeuristic raising only some of the present objections?
