I'm saying that code completion does not constitute AI and certainly isn't LLMs.

I then provided an example of why that isn't the case.

You decided to respond to this by pointing out that some LLM may be involved in some code completion. Although you didn't provide an example, so who knows if that's actually true, it seems sort of weird to use in LLM for code completion as it's completely unnecessary and entirely inefficient, so I kind of doubt it.

I just want to point it out for a minute, because it's sort of feels like you don't know this, code completion is basically autocomplete for programmers. It's doing basic string matching, so that if you type fnc it also completes to function(), hardly the stuff of AI
