American drones are extremely high priced, good, but not great. They are not that innovative. Israel, Iran, Turkey, and others have made some amazing breakthroughs combining low price cell phone technology with innovative designs to do great things (or terrible things depending on which side you are on). The technology is all in its infancy, so sometimes it is great, and sometimes it fails completely.
Israel and Turkey are slightly selective in who they sell their weapons to. Iran is the opposite. They have made their drones open source, which means anyone can download their designs and make themselves a drone fleet.
No one knows who will develop swarming drones that use AI, and ad hoc networks... But I am sure someone will. Maybe not this year, but within a few years.
Are drones being delivered to Ukraine from Israel and Turkey as I write this? Maybe. Are Ukrainians building Iranian style drones from downloaded plans as I write this? Maybe. Are Ukrainians developing their own drones? Maybe. Are the Ukrainians doing nothing with drones? Maybe.
