That sounds about the same as normal factory work if we're being honest, which is still around. Yes, it really does bore you to death. No, it doesn't make you incapable of thinking. Usually the people who take a crap job like that simply don't spend that much time on intellectual pursuits to begin with. What it does do is to drain you of all energy such that it's hard to get away from it to something more decent.
