Drones Reshape the War in Ukraine

For some time now I have wondered if new drone technology would start to dominate the Ukraine war leading to entirely unanticipated results.

This has now started happening, evolving, even dominating the battlefield according to this YouTube video:

Ukraine frontline: The killer drones changing warfare

How will this evolve now? What will this battlefield look like a year from now, two years from now?

And what will be the eventual blowback from all this impersonal killing?
