I mean plain old autocorrect does a surprisingly good job. Here’s a quick example, I’ll only be tapping the middle suggested word. I will be there for you to grasp since you think your instance is screwy. I think everybody can agree that sentence is a bit weird but an LLM has a comparable understanding of its output as the autocorrect/word suggestion did.
A conversation by definition is at least two sided. You can’t have a conversation with a tree or a brick but you could have one with another person. A LLM is not capable of thought. It “converses” by a more advanced version of what your phones autocorrect does when it gives you a suggested word. If you think of that as conversation I find that an extremely lonely definition of the word.
