Yes, and eventually they will.
They will also dogfight each other and human piloted planes, and the human piloted planes will lose catastrophically. Planes manned by humans are limited by human limits, planes manned by computers have only the limits of their engineering imposed on them.
We’ll also start to see this in land warfare. An M1 that doesn’t have to keep it’s crew alive can slap on even more armor without being any larger. Smaller, less armored units could be designed to take much over many infantry roles.
Machines don’t need to eat or drink. That takes out most of one major logistical hurdle. They don’t need rest longer than it takes to refuel/re-energize or swap batteries. No one is going to mourn the loss of a machine, making it more politically palatable to wage wars this way.
Einstein wasn’t quite right about WW3.
