Would there be small air superiority drones soon?

Drones feels like it's in early WW1 with pilots throwing grenades at ground troops. Would we soon see drones with guns designed for low level air superiority? Like a miniature P-51 with .22 machine guns.

Ukraine/Russia is scraping by and buy off the self stuff. But US/China should have the tech now or soon to make autonomous patrol drons that will shoot down enemy drones automatically.
