It may not be the End of History, but it now appears that we are now experiencing the end of armor as a viable military tool. Soon to come will be the end of ships of all natures, including aircraft carriers.
Tanks, surface ships, and manned aircraft face a problematic future. Much of the US DoD is obsolete.
Missiles, UAVs, autonomous subs, and other intelligent weapons systems are proving effective.
There should also be new classes of weapons. I think a low-observable, lightweight, high flotation, autonomous killer robot would be just the thing for spring warfare in muddy Ukraine.
I agree with you. Heaven only knows what will arise to take its place, though.
