The ideal situation

Computer words are very different from the words human beings use, because computer words have very clear, specified semantics. There is no ambiguity according to Warnier.

If you type the command he’ll do exactly the same every time. While with human words, depending on the context, or the intonation, or the body language, they can mean a lot of different things.
Logic words function in a structure and have a very precise meaning. In mathematics there is no ambiguity. If you give a computer a command, a word, you can trace back all the steps to see what actual gates are flipping at the processing. Computer systems can talk to each other and this can lead to negotiation, but in principle it is still the same complete reduction back to the CPU, the central processing unit, or the underlying network infrastructure. You can explain everything that is happening before it happens basically. In principle it is a closed system; there is no influence from outside. A user can influence the system, and doing so brings in the randomness, but what the system will do will be completely predictable. This would be the ideal situation.
