Smartphones are kinda dumb though. As smart as they are they are a tiny screen you need to hold.

Screens monitors tvs pads whatever are just glass that information is beamed onto.

Why not just use that same tech to be that same information in front of your vision. Cut out the middle man that is the phone screen. Isn’t that better ?

I’d love to have a heads up display but I don’t think it has much practical applications. Can see my heart rate my maybe my speed and my location of I need directions.

This is the same revolution that were phones. People like you said the exact same thing. Be dumb to look at your phone all day. Yet here we are.

Chicken and egg. Need the hardware to start off the software. Without useful reasons for it it will die. Price point too
