I read that part differently than you.
I do not believe the comment was directed at paramedics or any other emergency workers.
Rather that the plant would be full automated to the point that no human is needed for the normal operation of the facility. So not only the production line but also all maintenance and other activities would be automated. The "mostly useless emergency supervisors" would only need to do anything if something unexpected happened that the automation could not handle. We are not any where near that level of automation yet.
