I am not surprised, drone warfare today requires a lot of people and a lot of manhours, and it does not scale that well. Several guys are often moving the equipment on foot to get as close to the frontline as possible, so that the pilot can have a few shots at delivering a pretty small explosives to a target they might not even found. On the other hand, few conscripts can jump on a Grad and start shooting rockets on a whim.

That means only they need more shells at the moment than drones. Ukraine has capacity to produce enough FPV drones.

Artillery shells are not manned vehicles.

I was responding to, "entering into the era of drone-vs-human warfare," not defending manned vehicles.

Another way of saying this is "may well not be".

They work well together, so give them both.

Both work together. The drone finds the target. The artillery then destroys the target.

I’d guess they can reuse the drones most of the time?

Only reconnaissance drones and few heavy bombers. Mostly they use kamikadze FPV drones in pair with Mavic for surveillance.

That's another instance of quantity beating quality. It's the same type of thing.
