They are ridiculously complicated to operate. Teslas can't avoid hitting stuff on the road completely, I wouldn't feel great about having one completely automated and deciding for itself when to initiate nuclear war if it isn't in communications range. I highly doubt they were all sitting around drinking beers and not watching the road in front of them, but it would be good to wait until we have more information before throwing the sailors under the bus. > with crack seal-type units only operating them There already are highly skilled individuals that operate them. Seal team members are in limited supply and think it makes more sense to have those that are more intellectually strong run them. They are a deterrent and non-nuclear submarines have large drawbacks when in combat. China has become more and more aggressive and they have scaled up their nuclear missile silos a bunch in recent years, have been sprinting towards a large more effective navy and I don't think they will have qualms about using morally questionable tech.
