Just listened to this.
It’s sounds like Harnad is stating outright that there’s nothing an LLM could do that would make him believe it’s capable of understanding.
At that point, when someone is so fixed in their worldview that no amount of empirical evidence could move them, there really isn’t any point in having a dialogue.
It’s just unfortunate that, being a prominent academic, he’ll instill these views into plenty of young people.
Typo here.
