How is that? Are you saying that the current discussion on woodworking safety is muddled and based on belief more than facts, or that ANY evaluation of safety is doomed to be irrational? Because I disagree with the latter (I don't know about the former)

It becomes an arms race of safety. Are goggles enough? Shouldn't you make a robotic arm with remote camera and operate from a safe 100 ft distance behind a blast shield? (Cue Mythbusters) .

So nothing good comes of it, only an endless discussion of where the blurry line is drawn.

TL;DR - be safe. You should know what that means.

I think the idea is that there is a theoretical graph where the X axis is "effort to act safely" and the Y axis is "chance of an accident" and it's shaped like a crooked L and although it plateaus, it starts out at a steep angle. So there is some point in there where a certain amount of observational safety is optimal.
