I think it's a difference of degree, not kind. And, as you suggest, the degree of onboard control / adaptivity is probably a good spectrum. As things become more simple and robust, I would argue the degree of adaptivity will necessarily decrease, because adaptivity is required to handle situations off nominal, and those can and should be designed around.
