I agree.
The reason why I brought Witten as an example is that his hypotheses are
strongly supported by intuitive arguments.
The general word "hypothesis" includes both such statements and a more usual
case when there is no strong and convincing supporting intuition.

Yes.

You are right, since there is no proof, a statement can turn out to be wrong.
(it happened with Poincare's hypotheses).
