That’s a wrong speech to deliver to a cute girl asking how to make things better.
You’ve started with philosophy and economics and olden days.
If we want to explain today’s tech and possible directions of fixing it to “normal” people, we need to start with what they need to do that they do with smartphones.
That’s what businesses do too - they take something hard and suboptimal, make the road shorter and take their toll. Sometimes stealing part of what you are carrying on that road, or replacing it with their unwanted shit, or just stuffing their unwanted shit into your pockets.
So what we should think about is - what to replace their finger-poking box with, so that it’d be better fit for how they use it.
I’ve written my luddite idea in another comment. Split it into a few dedicated devices, much simpler in their essence. Since smartphones are used today mostly not as universal machines, and this difference can be optimized.
