I think this is just the latest chapter being written on asymmetric warfare........and I'd submit it is remarkably easy to avoid asymmetric scenarios as the sole super power of the world. We just aren't good at avoiding them until the citizens start grumbling. I might be alone here, but I don't think the $500 drone and bomb changes the face of warfare like the internet nerds do. Maybe for the grunts, but there are so many ways to counter that threat, it is astounding the russians haven't to a large extent.
I think something that often gets overlooked in the Russian / Ukrainian conflict is Russia's inability to establish air superiority / utilize CAS to any significant degree for various reasons - lack of proficiency, corrupt / incompetent leadership, lack of precision munitions require low flight profiles, effectiveness of western AA systems, etc.
Russia's doctrine was always tank-heavy, and drones are well suited to countering that threat when there is nothing protecting them.
Will it completely revolutionize warfare - by that I mean, our doctrine? I don't think so. Does it create a new threat (and capability) to address in joint warfare at the tactical level? Sure.
I would wager if a nation attempted to fight us the way that Ukraine is fighting Russia, it would look a lot like Germany punching through the Maginot Line. Don't interpret that to mean we would completely mop the floor with them just because it's quick - Germany took a lot of casualties invading France and lost a ton of tanks and aircraft.
