Because context, at least in my experience, doesn't seem to encapsulate the sort of dynamism that I'm thinking of. Conversations are flat and repetitive. It still feels like a very good semantic search more than talking to an intelligent human.

I don't know if they will replace most humans the way you're imagining. I think the industry has done a very good job of selling this point, but that they are still quite far from this.
