Yes, for a number of reasons:

- I am trying to learn about the topic at hand and trust a human's comment more than an LLM's guess - I am trying to connect with other humans to fulfill my social needs - I am maybe spending time to help another human out with a response because I want to help someone else - I am interested in the perspective of other humans

Those are just a few reasons. For each of those if it's actually an AI I feel I'm losing out on something.
