That's your opinion. Reality is somewhat different. LOAC still applies, but nothing currently stops the arming of autonomous drones other than self-regulation. First world or peer level adversaries might give lip service to the concept of AI drone disarmament, but come crunch time; they'll most likely use whatever assets they have available. Rogue nations will be completely unchecked. I expect, IMHO, that AI drone restrictions will be about as effective as current international chemical/biological weapons regulations.

As for the MQ-25, the US Navy fighter mafia is hell bent to extend the lifespan of carrier-based manned fighters for decades to come. Can you blame them? The horse Calvary did not embrace tanks or helicopters either ...
