You are silly. Very smart people at Skynet have already released media insisting that their automated Terminator security cyborgs will take over all shipboard security needs within the next 10 years. Most likely will occur aboard Norwegian or other Scandinavian ships first but will eventually take over the industry. Resistance is futile. This is happening due to technology whether you like it or not.
Remember these people are smarter than everyone else and they assure you it will happen. So get onboard silly Americans.
