supplementing our humanity..
This is exactly the problem. Supplementing x implies complete knowledge of what ideal x is. And what the "ideal" is nearly impossible to assess, since it require complete knowledge of future. I mean, what form of a "human being" will the most optimal through all of human existence? When you supplement without knowing the ideal, it has more chance to do harm than good.
using these tools is what makes you human, as without them, what's really the distinguishing feature that separates you from the apes?..
Ok. But is it the only thing? What about creativity? We have language. We can create great stories and beautiful poems in them. We can look into the secrets on nature and create immensely powerful tools with that knowledge. Isn't that more of a hallmark of being a human, than mere dependency on our tools?
And is there no limit on how much we are dependent on them. Does it make sense to trade of our innate capabilities in the long term, for minor conveniences in the short?
I had a friend who could easily navigate any complex routes and had all the local routes and short cuts in his head. I respected him for that. Now he cannot find way around a supermarket without GPS. A part of him, that once I respected as a human being, is gone now.
To me, nothing defines humanity more than the constant improvement of our race, our reach, and our capabilities.
You think our race is improving? Why? Because we have smartphones and have a massive and collective addiction to it?
and the largest accumulation of knowledge the human race has ever seen..
It is also one of the biggest Ad/propaganda delivery channels.
Easy access to information does not make a difference is the people does not have the drive to consume it. If you give internet to 10 persons 9.5 of them will use it for social media and porn. How many of the addictive smartphone users have you seen consuming wikipedia? I have personally NEVER, not even once, seen someone reading wikipedia on a smartphone.
