This is so dumb and goes against all the principles that enabled computers and smartphones to achieve wide adoption - the technology should evolve to fit the human. Not the other way around.
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.
Also, I find it funny you mentioned "there's no such thing as words [...] at the computer level". It seems you are the one in the need of a computational theory refresh. Grammars are composed of words, which in turn, are composed of elements of the alphabet set. So, in fact, not only there are words, computers are, above all else, word-processing machines. There are more innacuracies (physical computers being stricly deterministic, needing binary to accomplish inference, etc.), but let's leave it at that, unless you wish to press.
There's always jargon and other token words that holds no meaning in other realm of life. Even the alphabet today is mostly arbitrary gliphs.

Please refer to the formal definition found in wikipedia

I've not said anything about computers being strictly deterministic. And everything is binary at the CPU/GPU level. Even with specialized instructions, you still need to organize them into a proper algorithm and encode it and its data to binary.
Sure, but this is a discussion focused on how humans interact with computers, ergo Human-Computer Interactions, so I'm not sure what's your point. In the end, you don't interact with your computer (in the physical sense) through a 2-key keyboard.
> Please refer to the formal definition found in wikipedia <link to CFG article>
When I mentioned grammars, I was talking about formal grammars in general. Still, I made a bit of confusion, since formal grammars only define the rules, whereas formal languages are, in one of its definitions, sets over strings/words.
Not that this means much, since the point of grammars is to define languages. As such, grammars (RG/CFG/NG/UG) stipulate the words that a language accepts. Words are important to computers (both in mathematical theory and in material reality).

My bad, that was my misreading of "formalized".
> And everything is binary at the CPU/GPU level. Even with specialized instructions, you still need to organize them into a proper algorithm and encode it and its data to binary.
Poor phrasinf on my part, but the "needing binary to accomplish inference" was supposed to be read in isolation. Still, computers do not require binary to operate. There are non-digital computers, both in history and being explored today. There are experiments on using trinary for optimizing LLM inference, for instance.
