25 years ago, sure: online shopping/banking, email and chat -- these are all things my Blackberry or Nokia could handle. The touchscreen smartphone hasn't really moved the needle much in that regard.
And I basically agree about sort of time saving, we got smart phones, which I think was of questionable benefit compared to the invention of computers, the internet, and cell phones in the first place.
Uber has saved me a remarkable amount of time.
More-generally:
When I lived rurally (in college) cabs had to be booked in advance, that's just common sense.
So much time was saved you don't even realize it because most of the above was just practically impossible to do before - and frankly beyond the scope of what any human actually needs. But the scope crept anyway and now they're all normal parts of modern life taken for granted. As for where that time went - capabilities exploded, but any spare time also got eaten by tighter work hours from a more competitive market. That's capitalism for ya baybeeeee
