I think the biggest hurdles to widespread adoption are ease of connectivity (getting pics and videos “out” of glasses and onto phone/laptop/cloud), ultra high def images, size of on device storage, and battery life. Those are tough, given the form factor. But, if cracked, these will be huge.
Google Glass remembers…
In Switzerland we have a nice law that forbids people filming others without their consent. And law is actually enforceable here, fines are juicy and repeatable offenses punished harshly. I personally wouldn't outright punch in the face a person wearing such glasses but asked them to stop wearing them around me and my kids, and where it goes further depends on them.
Also, why is the design in those so weird? They look like kids glasses for 2 bucks, all photos seem like they are not sitting on the face well, zuck including.
Quick to justify violence for someone that opened with "the government will protect me with fines after the fact". Just noticing.
This is exactly why regardless of how breakthrough Meta makes their wearables, it will never reach full market potential as their brand will always be known as a privacy nightmare. Apple is going to win here if they can get the price right.
VR I think most people can rationalize it as these headsets are used in very controlled states, like at home on the couch or living room - but for Meta to convince people to use this in their every day life..hard sell.
