What is the next step in the evolution of Armor Branch and tank warfare? Or, has the technology peaked?

Drone tanks?

I thought wars were no longer conventional What about ARMOR Satellites!

Technology hasn't peaked. I haven't seen accurate numbers yet, but improvement of fuel engines has moved nowhere. It has been estimated that we will still be using fossil fuels and other liquid (heavy and inefficient) fuels to move almost everything until past 2040. The problem is that much of the world is not united. Much of it is not aimed toward technological advancement. The U.S.'s space program went to the crapper years ago.
Like we've all seen in the movies, future Earth has tech relying on nuclear or some other futuristic energy that we've discovered. Navy subs are nuclear right? Some of them at least. I'm not a Navy soldier. Until the people of this planet can unite for all, I doubt we'll see a significant leap in military tech.
