Good estimate! But no. Not at all. The principle reason being this: Robots are created by humans - beings that don't fully understand their own bodies, brains, or the world around them in general. Janets are created by the Makers of Light, Darkness, and Everything, who understand everything because they made everything. Therefore, while robots are limited by the incomplete nature of man's intelligence, Janets have no such limits.
To illustrate: Robots are to me what these are to this.
