I misread the title - saw 'lens' and thought this was about Apple's coming AR eyewear.
But gave me a great idea: Apple AR eyewear spots someone you're interested in; id's the person; reviews their social media for dating/marriage status, likes/dislikes in a mate, and comes up with a score - e.g 48% - that you have a shot at getting a phone number or date.
Who's with me?
