I’d use them to subtitle everything because i’m deaf

Not true. I've had my eye on a pair for awhile that has no camera, only microphone, but has a HUD. Having navigation, an irl minimap, without having to keep your phone out is nice and has some actual positive safety implications. Also, this might mean less to Americans, but as someone living in Europe, having in line translation is really, really cool. Could almost sell it on that alone. I've heard some deaf folks are also using it to help understand people by augmenting their lip reading (which usually doesn't get all of the information across by itself) with summaries that the mic picked up.

I've only held off because the pair I was looking at seem like it isn't quite there yet in reliability, but there are definitely some pretty big use cases I can think of. I would 100% get some of these without a camera.

there's really no reason to have a screen on your face

Look around. People have a screen on their face 24/7. Currently they need their hand to hold it there.

Maybe you mean there is no need for a camera on your face. That I agree with.

Get away with watching YT at work? Reclaim hours of my life, that's my end goal.

So there are certainly some valid use cases. They could be useful for surgeries, engineering design work, surveying, etc. None of these have you wearing them all the time or in social areas through. It's a niche product they need to focus on those markets and stop trying to force mass adoption. It's the same as AI.

Lidar, rather than a camera. Allows it to create a 3d model of what’s in front of it without being able to take pictures itself
