So if you want to quickly check/reply to a notification you'd pull out ski goggles, put them on, then take them off?
In my case I bike a lot so they’d be doubly useful assuming latency is very low.
People may get seriously injured if they're actually wearing these things all the time. Even if they're 100% reliable you could imagine someone getting a low battery warning running down stairs to fetch their charing cable only for their vision to shut off as they're running down the stairs...
Even if small and light I doubt that they’d ever change that messaging.
Or, you know, this being the shitty dystopia we deserve, probably it'd just advertise the nearest McDonald's.
If you get a notification, you can respond straight from it.
You can also see your phone through it too to respond.
