killer drone swarms would just lead to hardened buildings tho, and to overcome that they have to move further up to the right to be feasible (ie, they must be drone carrier drones) and the AIs have to learn to recognise soft points that can be widened enough to permit access... while also having to carry those rockets.
i would argue that drones and AI drone swarms are actually next after strategic nuclear, because they are fundamentally missiles, at lower velocity, that can do surveillance, sabotage and assault, and support (ie mesh networks) all in one.
idk if you ever read any Bart Kosko but he did a lot of work engineering ballistic missile systems and he basically said once an army has these, most of the rest of the army doesn't matter.
what's happened is the next phase, where scale means being undetected, and AI means autonomous, heteregenous drone deployments that can take on multiple roles, as well as failover between them (eg, most drones can probably carry mesh routers)
