Why do they have all them fingers and toes and hair?
Cause they can focus on the job.
I see no paperwork.
No re-arranging safety gear.
No zoning, ie this pen needs to go here, this screwdriver needs to go here, this paperclip needs to go here.
The machines are predictable. Ain't no one gonna walk past in a high viz jacket, which the machine will detect and think it needs to act.
But probably most of all: They know those machine are deadly. There's no false sense of safety.
