Do you work in the Coast Guard?

I think that the future for the drug smuggling is computer controlled submarines, and I'm not even talking about AI. I think drug producers will pre-program a route for a submarine that will autonomously navigate until the destination where it will be picked by a receptor.

I read that it's extremely hard to spot submarines, I can only imagine the kind of things that will be smuggled once there are functional submarines of the size of a big fish.
