I don't think Musk would disagree with that definition and I bet he even likes it.
The key word here is "significant". That's the part that clearly matters to him, based on his actions.
I don't care about the man and I don't think he's a genius, but he does not look stupid or delusional either.
Musk spreads disinformation very deliberately for the purpose of being significant. Just as his chatbot says.
