I read about the US Navy's work on autonomous ships. One big challenge is the lack maintenance. Sailors can perform periodic and break-fix maintenance throughout the journey, and if something unpredictable happens, they can handle it. The autonomous vessels need far higher robustness, not only to function without maintenance for months at a time, but reliably enough that few of them end up lost or stranded at sea.
