Agent warfare is going to be a very big deal.
I think people are underestimating how strange cyber gets when millions of agents are acting on behalf of individuals, companies, and states.
At nation-state scale, cyber offense and defense starts to look like autonomous swarms: probing, exploiting, patching, deceiving, countering, and adapting at a pace that is impossible for human minds.
The advantage will go to whoever can close the autonomous kill chain fastest.
