This is like saying the arguments put forth by a schizophrenic lawyer are rational and correct.

If the context is that it's a tool, correct is defined as reality within the context of the use of that tool. If it's to find facts, it can be incorrect, since the context of a fact is reality. If it's writing a story, then "correct" would be based on continuity, etc.

If you're using it as a tool to generate words related to previous ones, then sure, it's always correct, but that's not probably not a useful tool for most people. But, being a next word predictor doesn't mean it can't also be a useful tool in real world contexts. There are, literally, billions of dollars being spent on pushing them to be more "correct" in more contexts, so it's a useful concept being considered, even though they're "just" next word predictors.
