I just don't see heavy armor such as tanks is going away any time soon, because of engagement range and maneuver capabilities, Russia failed to utilize ISR to counter anti tank threats (eg. recon drones and probably some infantry elements) and in general seems like failed miserably in combined arms maneuvers (where tanks provide only support to infantry in near real time coordination).
