> we know not to do the thing that makes them explode. We collectively know a lot of thing, but as soon as you leave the opportunity to a human an accident will happen sooner or later. We know not to start heavy machinery while there is a maintenance technician inside it, but it still happens. This is why we have safety lockout systems, to avoid an accident even if we know better.
