Wikipedia tells us that "The concept of the uncanny valley suggests humanoid objects which appear almost, but not exactly, like real human beings elicit uncanny, or strangely familiar, feelings of eeriness and revulsion in observers." That's where we are with chatbots now, and why it still seems reasonable to suppose we'll want to interact with a human for things that require that personal connection, including learning and education. But chatbots are not going away, and they go with AI "like chocolate and peanut butter", which suggests they'll get better, and maybe good enough to get past the uncanny valley. What then? This article (like so mnay others) suggests "that doesn’t mean they can replace human employees." But why not?
