Why does it matter? If an 8 year old wanted to pontificate on metaphysics, I would gladly listen to and engage them. And maybe I would learn something. Not all exchange has to be professionally compiled knowledge being bestowed to laypeople. I kind of think everyone can learn something from everybody on most any topic.

Within a discussion I think it makes sense to interpret statements based on the speaker and their epistemology. But that doesn't mean you can't have a conversation.
