It can be simultaneously true that smart glasses are a technological marvel and a privacy nightmare.

It's also important to consider that while many places have some legal framework along the lines of "no reasonable expectation of privacy in public spaces," there's a social-psychological gap between that and the presumption of being constantly recorded, be it by other private individuals or governments.

Because of this, my view on this technology is that it's a net negative in society, and generally unhealthy.

They were better off being left in dreams, because there you never have to actually think of the consequences.

Like Star Trek holodecks. They seem amazing at first, but only because the weirdest it ever got was a sweaty Lt. Barclay, a creepy Cmdr. LaForge, and a safe-for-TV sleazeball named Quark.

In reality, if you could "jack in" to a self-controlled Matrix, or walk onto a holodeck and make anything you wanted feel real, it would be 24/7, 100% the unhealthiest invention since the nuclear weapon.
