@cstross Nothing says you can't build or power a mobile jammer that puts out several MW; nothing says you can't build defensive drones, nothing says the sensor quality contest has even happened yet (can the attacker spot the target before the target spots the attacker and responds?), nothing says the trend to precision fire over volume of fire can't produce precise volume of fire. (the move to precision is economic.)
@cstross And, crucially, drones do not function as decisive mass; they may never, since drones are slow, as well as cheap.
We can see that in Ukraine very clearly; Ukraine struggles to convert their drone advantage into victory. Things are going well so far in the current excursion because they decided to abandon a political convention to exploit the opportunity to maneuver. "Assault troops shooting the shit out of disorganised rear-area troops" has been the ambition of cavalry for centuries.
