I have no surveys to back this, just intuition. But I don't think one order of magnitude is enough to counteract the fact that people don't feel as if they have control over their own mortality.

i.e. it'll have to be a lot better than just one order of magnitude before people can be swayed towards putting their lives in the hands of a robot.
