> It will remember all your activities, help you find your keys and objects, remember what you bought when and if there's still toilet paper in your bathroom, etc. It will make helpful charts and statistics about your life, help to optimize it, notice if there is some product that it wants to advertise to you based on your activities etc. It's all going to be packaged and sold to ad networks. You will see AR ad objects floating everywhere, depending on what you do.

Presumably only if you wear it.

Yeah but maybe slowly things will require it. Just like restaurants today that only have a QR code but no physical menu, maybe a bunch of stuff will only be virtually present in augmented reality in the future. If you take off the glasses, signposts will be missing, etc. It's hard to imagine now, but maybe it would be hard to tell someone from 50 years ago that entire stores, subway ticket machines, bakeries etc. will be cashless and people will tap their phones to pay, and if you have no phone or card, you're screwed. Or if you have no Android/iOS app, you can't book appointments with certain govt offices etc.

Things that start as optional and convenience only can slowly become essentially mandatory. And then if you are already wearing it, it will push the ads.
