True, but take into account that plants need to be able to fly/fight with instruments only and without vision.

Also dogfights are much rarer now, most people just fling rockets at each other (so you know how much these cost, a b200 seems cheap in comparison)

Autonomous flight is significantly easier than autonomous driving. You just fly between points in space, and there's nothing but air inbetween. The ground control handles most of collision avoidance, and if that's not available, it's easily achieved by moving 300ft/100m up or down.

You don't need a super powerful GPU to do computer vision. There are cheap small devices that can do it.
