I donāt even know why anyone would think this.
Youāre telling me, if you got a phone call at 3 oāclock in the morning, no matter what kind of phone call it is. Emergency, someone needing to talk, whatever, it would be more convenient to put in some contact lenses to answer it than pick up the phone?
I used the 3 AM example as a worst case scenario, but it goes for many others as well.
People are not going to want to keep contact lenses on their eyeballs 24 hours a day, seven days a week. People are not going to want to keep glasses on their face 24 hours a day, seven days a week.
Do you really think the phone will be the primary UI device for the rest of time? Once AR glasses (again, thin, lightweight, affordable are key here) are available, do you think people will still want to walk around the streets with their heads buried in their phones?
A lot of people wouldnāt need computer monitors at their desks, or to carry around laptops anymore! Just a keyboard and trackpad.
If we could develop the technological capabilities (and admittedly itās a huge if) to make contact lenses with displays in them, then surely we could make them comfortable too?
I remember when the Apple Watch came out and many people said ānobody wears watches anymoreā. A lot more people do now! If there is enough utility and value in AR glasses more people will wear glasses too.
Also note that people didnāt stop using their phones because they had Apple Watches. Iām sure glasses would be the same for a long, long time (and would have to be as long as processing is done on the phone, as it surely would be in the beginning)
The future is a device ecosystem to cover our senses and provide access to computing and networking. We already have AirPods, Apple Watches and HomePods as accessories and alternative interfaces. Iām sure that glasses would also start off as accessories and youād still need the phone. (Apple has recently acquired a silent speech-thought to text company so that could be another interface in the nearish future.)
Looking further into that future, if iPhone tech can be built into glasses, maybe thatās enough for some people. That 3am calls comes in and you donāt want to put on glasses, you could also answer it by speaking into the air to the nearest HomePod or popping an AirPod in. For those that prefer to hold a headset to their ear Iām sure such accessories will exist.
