Especially you can already notice many countries to be very excited by cheap and fairly simple drones successfully used against very expensive vehicles. For example Iran being actually on the forefront of that tech now and embracing it with eagerness (to be fair, Iran had keen interest in drone warfare for years by now, so it's logical). Sure, in case of Russia it is effective because Russia have good military infrastructure, doctrine, logistics and support to base those on, but those still look like some measure of equalizer.
