I think the bigger problem with both is that they're tech demos rather than products.

I got to demo Google Glass at a tech meetup once. It wasn't the first release, so there had been time to work bugs out. It rapidly overheated after taking, and looking at a couple pictures, and the battery life was abysmal. It demonstrated several capabilities that will probably be included in useful products in the future, but it was essentially unusable.

I bet in a decade or so, smart glasses will take off. As soon as they're actually useful, the social resistance to them will get worn down.

The article agrees:

> It is telling that this product comes from the same people who brought us Google Glass, an ugly, invasive face-mounted camera that evoked hostility wherever it was worn.

Yup, same with Snapchat spectacles! Although Spectacles did try to play with the coolness factor at least.
