Someone is going to do it and make a lot of money, I'd prefer it to be the company that isn't actually an advertisement company pretending to be a phone manufacturer.
As phones become more and more powerful over time, I can see my phone replacing my iPad or (perhaps) even my laptop - but I don't see them lasting as long as that. They're smaller (and therefore more prone to being dropped), with you constantly, and are mostly glass. Even with technological progress aside, I would expect most people to go no more than five years between replacements.
Our current lifestyle of buying a new phone every 3 years is incredibly selfish and is destroying our planet.
I always joke that the next iPhone will probably be made out of porcelain. I'm not even sure that would be worse.
Also, are you willing to accept increased unemployment when less employees are required due to diminished demand?
When the last tree is cut, the last fish is caught, and the last river is polluted; when to breathe the air is sickening, you will realize, too late, that wealth is not in bank accounts and that you can’t eat money.
There are unlimited jobs that require virtually no consumption in areas like research, art, teaching, music, wildlife conservation and so many more.
Most of the areas you mention are funded by other revenues, either directly by companies, or indirectly by governments taxing revenue or income. Without revenue most of these areas will also see reduced budgets.
With battery replacements and iOS upgrades improving performance, it seems like nobody has done more than Apple here, and indeed their stock price is even suffering for it.
What more are you looking for, honestly?
