I don't think it's the glasses that are the problem.
I can see lots of benefits.
Some could be life-changing (e.g. "correcting" macular degeneration).
Most people use them to take calls, listen to music, or reply to texts via voice without pulling out a phone. This could actually make people safer.
Most can translate - whisper the translation into your ear or project subtitles directly onto the lens.
This subtitling could be great for deaf /hard of hearing..
You could also read notes while giving presentations without having to hold them/have them in front of you and navigate around places without looking at a map/phone.
"Point-of-View" videos (like cooking, mechanics, medical procedures etc) so you can see what the demonstrator sees.
A technician/surgeon etc can "share" their view with an expert in another place. The expert can then draw, say an arrow on the the display and talk to the person attempting the procedure. Scans and x rays etc can be superimposed over the patient in surgery...
Let's not throw the baby out with the bathwater.
