I think it is a symptom of prolonged warfare. The more the conflict drags on, the more probable it is for requirements to change from "A highly sophisticated state of the art tank" to "a tank". Same with infantry, both sides will have a much lower percentage of trained infantry the more this thing continues. And this btw is usually the reason why countries that fight for a long time dont necessarily have the best quality troops (as another example, see Iran-Iraq war).

T62 will still be useful as a modern day Stug IMHO. And for the type of warfare we witness, you dont really need an Armata, you need any moving cannon.
