The somebody follows the permission links and breaks into the robotics computer and deletes things. Maybe you could argue that it is the fault of the administrator of the CSD machine, but in fact there was no administrator of the CSD machine because he had quit to form a startup company. In fact, it is nobody's fault. No solution involving authority, management, or administration will work in a network that crosses organization boundaries. If people keep designing technologies that are both convenient and dangerous, and if they keep selling them to nonspecialists, then expedience will always win out over caution.
Convenience always wins, except where it is specifically outlawed by authority.
To me, this is one of the primary RISKs of any technology. What's special about computers is that the general public does not understand them well enough to evaluate the risks for itself. It suggests why even defining safety is so hard. When you are lost and ask for directions, never ask just one person for directions. Ask two people, and you have a better chance of getting to where you want to go.
