A key aspect of Armata seems to be the integrated crew compartment seperate from the weapon system.
That does seem sensible in terms of weight reduction and crew protection and is something the next gen tank is likely to have.
The west seems more leery of fully automated turrets, the US walked away from MGS for the manned M-10, although less so at autocannon level.
As for armour, defence against IEDs and handheld threats imposes a need for it, albeit not to defeat incoming 120mm perhaps, and active defence if reliable is lighter although needs ammo and complicates close work with dismounts.
Issues with Armata seem more likely to be electronics given Russia is a backwater wrt producing these, and software integration of modern complex systems which the Russians have never really done before (they have shed loads of systems, but not integrated). I’m sure they’d use it they could, embarassament at losing it would be trivial given the embarassment so far!
