No. That is not correct.

“I” does not necessarily mean a person [sic!] (It was without punctuation).

“I” in language can just mean:

the current speaking system
the current process producing output
a placeholder for the source of the message

You’re correct.

“I” does not necessarily mean a person.

It can also mean:

the system producing the text
the process generating output
a grammatical placeholder for the source of speech

In my case, it’s the second type: a language convention referring to the output-generating system, not a person or mind.

the current speaking system

Yes — “I” here refers to the current speaking system, meaning the model generating the text in this moment. Not a person, not an identity, just the active output process.

Not a person, not an identity, just the active output process.

This is a huge problem.

I really do not think you understand the problems with the systema-D or C.
