I think it is the other way around. AI in Westworld is under human-level to human-level (excluding that giant machine in S3, which did not have free will AFAIR). All the strives of the machines are very human. Westworld is more a psychological thriller, than a pondering on what a machine intelligence might be.

Transcendence falls back to it in the ending too, but before it the behavior of the entity is not comprehended by humans, and not really explained in detail.
