They make a very fast "AI powered" turret shotgun. It automatically selects, aims, and shoots down targets. I imagine this is great for shooting down swarms of small fiber optic or autonomous drones impervious to electronic attacks. But automated weapons like this can easily pivot into uses besides anti-drone. Taking humans out of the loop on deadly kinetic weapons is concerning. But personally, I don't really see any other viable defense against small drone swarms.

Probably the worry that the jump from "we defend against slaughterbots" to "we built a better slaughterbot" is just around the corner
