For me, it’s Apple doing R&D in the public square. This is not a mainstream product, but they are shipping it now to learn a great deal and to prepare app developers.

The tech is crap at this time. Too bulky, batteries too inefficient and the form factor like @kr says is terrible. But they will eventually end up on a new & improved product before the end of the decade.

What comes of it could be interesting. Glasses that you never need to go to the doctor again, they improve your vision instead of constantly playing catch-up to your prescription. They provide extra context when driving, and point-out things that we wouldn’t otherwise notice or that may have been forgotten. I.E. where I last left my keys.

The tech will never be transformational though. It’s a replacement product so is not going to improve productivity in my opinion, not in isolation. It might just help us look-up and stop us slouching on our phones & computers more, and replaces the need for headphones with bone-conduction sound. But I’m way more excited about other applications of tiny tech/electronics than a pair of smart glasses or doomsday goggles.
