To your first point, I'm not convinced that's true. People augment their lives in lots of ways that don't seem to reduce safety. A few examples off the top of my head: simple "dumb" cruise control hasn't lead to more accidents. Parachutes have auto-deploy features if the cord isn't pulled by a certain height. Scuba divers use dive computers that basically eliminate the need to learn dive tables (and beep at you when you're doing something dumb). Apparently passenger jets are highly automated (I'm out of my depth on that one). These are all on the spectrum towards automation and have only been helpful. Do you think the problem occurs as you approach 100%? Like an uncanny valley in the 99 to 99.99% range?
