Tanks will get smaller. There will be 3-man crew tanks and later 2-man crew tanks will take over. UGVs will be deployed with tanks. There will be tank pilots similar to fighter pilots. One of them will drive the other one will be responsible for controlling UGVs and weapons. AI will help tank pilots to keep everything in control and to keep the workload of pilots in check. A small fighter-like cockpit is all you need with just 2 pilots and this will pave the way to very light tanks(40t) without sacrificing armor protection.
Excellent post explains the future.
