I don’t think that drones are necessarily the only answer to the “expensive weapons with expensive to train crews” problem.

Expensive weapons lead to cost boondoggles and economic asymmetry, eg $10k in modified COTS drones can defeat $MM in conventional armored vehicles.

We should be re-evaluating our weapons systems economically as well as doctrinally.

For example, would our Navy be more effective with thousands of relatively inexpensive small platforms that could do commerce raiding, interdiction, air defense and so forth (destroyer type jobs) than with our expensive and rare large surface combatants?
