comment morphisms in $Vect_k^\otimes$
Thank you. I want to determine the automorphism group of the forgetful functor $Vect_k^\otimes \to Vect_k$. (It should be trivial.) Since the automorphism group of the identity functor $Vect_k \to Vect_k$ is $k^\times$, what is the additional structure for $Vect_k^\otimes$ that eliminates the extra automorphisms?

"Scheme" implies that the topological space is sober, but I think this is the only assumption.
