So, we're mostly engineers here. Let's use an engineering metaphor. We're trying to achieve interpreters communication. We need to send some piece of data.
We'll simplify down to three elements: the serialization process, the communication medium, and the deserializatiom process.
The serialization process is our speaker. How well can we represent our data in a line protocol? Do we lose fine details, maybe data types get converted? Do things get entirely mistranslated, like a zero value becoming a null? A speaker can do a poor job converting their thoughts (data) into words (serialization format).
The medium is how the data gets exchanged. Maybe details are lost (again) via headers being stripped, or sourced getting over written. People can lose a lot of information based on medium as well, in particular text based communication, different cultural context, or just a noisy room.
Finally, there's deserialization. No matter how well formed your line protocol, how reliable your medium, the receiver can have a library that incorrectly decodes the data. Ints can become strings, zeros can become nulls, formatting can be lost.
So, as you said the speaker is responsible for being thoughtful and careful, but even if they are the listener can get the wrong message due to their own flaws or even just circumstances. And that is leaving aside intentional misrepresentation, which is a problems unto itself.
You forgot 99.99999% of what matters when communicating: the context/culture/shared model of the world. You can send a single word and in one context it is a death sentence and in another context it shows that you are part of the group.
