"> 600 million years of evolution did not prepare humans for traveling at 60 mph (much less controlling two tons of steel and insuring the safety of their children, while doing so), nor did it prepare humans for sitting in front of a bright light pecking at keyboards for hours and hours on end."

This argument is missing the point. True, evolution didn't prepare us to drive cars, however it did prepare us to spend long periods of time focusing on objects at fixed distances and then changing our focus on the ~hundreds of milliseconds timescale. It also evolved us to allow independent movement of limbs during this process, essentially what driving a car is. This same argument could be applied to typing at a computer (without the need to change focus very quickly).

I think the point is that cinema in 3D forces us to change the location of our focus very rapidly (much faster than hundreds of milliseconds) for long periods of time, something that we are not equipped to do. For a physical activity like sitting our muscles are malleable enough to adjust to a sedate lifestyle, but to increase the speed and duration of rapid eye focusing would most likely require rewiring the brain. Perhaps if we were raised in this pseudo-3D realm our brain could adjust, but adults brains aren't wired to change like our muscles are.
