Yes, but you're speaking to a computer, not a person. It, of course, runs into the same limitations that every computer system runs into. In this case, it's undefined/inconsistent behavior when inputs are ambiguous.

Yes, but part of the value of LLMs is that they are supposed to work by talking to them like a human, not like a computer.

I could already talk to a computer before LLMs, via programming or query languages.
