I suppose I might be interested to wear an AR glass similar to an episode of "Black Mirror" where they can display information about a user given their social media. But isn't that pretty creepy?
Which is why I am thankful Apple is making this set of AR glasses, and not Google. Because Apple gets good design while Google doesn't. That's why the Google Glasses flopped, because Google just didn't have a flipping clue what passed for good taste from the consumer's perspective, and what didn't.
Not to mention that any such piece of tech from Apple will likely have an easier time winning over the consumer than if it were released by Google, Facebook or even Snapchat. The trust and branding power is there. Apple has also been working on its own proprietary tech such as W1 wireless standard, custom processors, Face ID etc and I believe these will all pay handsome dividends when it comes to wearables, where you will want solid wireless connectivity, power efficiency and a form of hands-free control.
Apple will find a way to have the AR glasses meaningfully augment our vision, without any of the inherent creepiness or privacy issues you find being mentioned into those sci-fi movies. That I have no doubt.
It's no surprise iOS 11 emphasised AR. Apple is using their iPhone market share to mainstream AR and taking this opportunity to find out what sorts of AR resonate with the users, and which don't. Just like how the Apple Watch took on certain features of the phone where it made sense (such as Apple Pay, fitness tracking and actionable notifications), I believe that's what the AR glasses will do as well. Take on additional functionality from your iphone where it makes sense given the form factor (eg: what tasks are handy to do on a phone but you find a pain to have to keep taking your phone out and unlocking to do?).
The parts are all there. What's left is for Apple to put them together when the time is ripe and release the product when they feel the market is ready. And you can be sure Apple will prime the market prior to this.
Just another page out of the classic Apple playbook. You can see it coming a mile away; doesn't mean you can do anything to stop it.
