Google glasses, I think it’s death was mainly because it looks nerdy aside of course the huge privacy concerns. Which honestly don’t exist now. Look at twitch streamers streaming everywhere. People installing cameras at their home and connected to the net for the world to see. Now we are going hard with VR/AR even Apple has a product for it.
Yes, streamers might a bad example I admit but in terms of general population being privacy centric. I doubt most people don’t really care until ofcourse it affects them if we do we would have huge backlash with Amazon Echo, Google assistant those stuff won’t take off. Baby cameras, IP cameras installed in their very homes those things are a huge privacy concerns yet they are still here. We have TikTok/ Vine which people voluntarily submit videos. Theres Pokemon GO which prompt people to use their cameras to catch Pokemons. Not knowing if those image captured might be stored and analyze. Smartphone themselves we have no idea if that thing is recording us. I think Google glass failed simply because of its market which were rich and fashion centric did not like it. Compared to it’s competition who still seem alive today.
