The core technology is impressive, and has legitimate use cases.

But that doesn’t outweigh the enormous privacy concerns these devices raise. They aren’t being angled as an accessory for specific activities, but as everyday wearables. If smart glasses like these became common they would be unavoidable, creating leave of intrusion that’s concerning even without Meta being involved.

As a cyclist, this is a terrible sell. I already have tech which does all this, and probably does it better, for less.

I don't need a HUD constantly in my face obscuring the beautiful views. I have sun glasses which fit well with a helmet and wrap around my face to keep the wind out.

I have a cycling computer, which offers GPS turn by turn, and pairs to power meters, heart rate and radar light. It is mounted on the handlebars in an easy to view place.

I have bone conducting headphones for music.

All of this is significantly less than $1000, and if something breaks, I can replace it all individually. I also don't have to wear ridiculous looking sunglasses to listen to my bone conducting headphones.

I agree that head mounted displays can be useful, I'm contemplating getting something like it, but just no cameras, please. not in the frame, not backwards, not anywhere.

Sell your bike to afford them. Easy. It's another pointless gimmick, like 3D TV or the Metaverse and virtual shopping. Zuckerberg had one idea and got lucky, it's been wasting money since.
