We communicate with other humans using voice and three dimensional hand gestures. To use computers and early phones we had to learn to operate new input devices: keyboards and mice. Later with touchscreens we moved to two dimensional hand (finger) gestures. We're barely making voice commands work with our devices just recently.
Then, a large number of humans are figuratively tethered to their desks because the devices need power and stable internet connection. Mobile devices break this relationship a bit but you still need to charge them and be close to some sort of access point. In any case, the devices encourage sitting in one place for hours at time.
And this is just computers and smartphones. Humans adapted their entire lifestyles and transformed the landscape to cater to cars.
Was it? Think first about what it replaced. Lots of manual computation in bookkeeping and financial sectors. Telegrams and snail mail moved to email. Typesetting in books and magazines became easier and widely available,…
If there’s one thing that you can’t say about computers is that they’re limited.
The context was that technology should evolve to fit the humans [not the other way around]. And if contemporary technology didn't have limitations, it would be correct.
But it did and humans had to adapt to the computers. Humans had to develop and learn special languages so they could communicate with computers to do all those useful things you mentioned. Why? They were limited in understanding (or parsing) human languages. It took us decades before we could talk to computers in human languages. We're getting pretty close - especially in the past few years - but there's still some friction.
You may need to revisit your computation theory courses. Computers are the embodiment of a mathematical model and thus the inputs and outputs are formalized.
Do you just hold a pen and words are written automatically? Do you just hover your hands over a piano and have the moonlight sonata played? No, you have to do precise mechanical movements because that’s how the output is realized.
There’s no such things as words, sentences, keywords, statements at the computer level. What it does is symbol manipulation. You provide it a string of symbols, the rules for the manipulation, and it will provide a string of symbols as the output.
What symbols, what rules, are completely arbitrary . We just found that {1,0} are all that we needed as the set of symbols and that Context-Free Grammar is perfect for specifying the rules.
We still need to encode everything down to binary (ascii, unicode, bcd, floating points, pixel formats, PCM,…) and use a programming language (as defined by a grammar) to get the computer to do anything. Inference is made possible by those two mechanisms. It’s not a new computation model.
