I think our children won't be "anti-smartphone" in the same vain as we are not "anti-mainframe"
And the idea that we will jump to having our devices being able to read our mind seems like a stretch.
As VR and AR progresses there are great new features like hand tracking, which allows for even higher precision than swiping on your phone. I agree with you, interacting with things through your hands is really intuitive, but I don't think we have unlocked it's full potential.
It’s possible that future technology will make it more useful, but on the current trend it doesn’t seem likely that AR/VR would surpass even my Apple Watch usage, let alone iPhone.
Smartphones won’t go away. Yes, wearables will replace some use cases – just as personal computers replaced some mainframe use cases and smartphones replaced some personal computer use cases. But smartphones will continue to evolve, just as one can draw a line from time sharing on an IBM 709 to spinning up a Kubernetes cluster.
A smartwatch can give directions, read and reply to messages, look up information, display schedules, and take pictures—all without taking my attention too far away from the real world. Anything longer I may as well do on a computer or tablet. I wouldn't be able to read the news or random forums, but the inability to do that 24/7 would be healthy IMO.
I don't forsee a future where smartwatches could replace smartphones for everyone, but I do think they could replace them for a lot of people, me included.
And, society can adapt. People used to talk on the phone in public constantly (and still do to a large extent, just less). This would be far less intrusive.
† For what it's worth, this is Google's AI. Rebble, the community-run service that lets Pebble's operate post-shutdown, chose Google for voice dictation, and as a result its more accurate now than it was originally.
Children born with smartphones around see them as ordinary and probably less addicting, it's what comes next we need to worry about for them.
Edit: Observing their behaviour, and my own (and other adults), I'd speculate that they are inherently addictive rather than simply new and shiny (I don't view them that way any more). To be honest, I find this pretty self evident.
At one point, we paused the movie due to an ambulance outside, and the boy lept from the couch to his phone to get his little fix.
People don't use phones to look cool or generally don't think about the style of using a device. It's not a trend people are following. They want the entertainment, function or stimulation from the device. So if electronics somehow become unstimulating, boring or useless to children, maybe then.
Netflix/streaming also encourages large stretches of being glued to the screen, which isn't always great.
Children will always want all of your attention, and their play is frankly mind-numbing. Due to the COVID situation, I am entertaining my toddler 14 hours a day 5 days a week and I find it impossible to stay engaged for more than a few minutes playing a child's game.
