We have to look at this like how we've been talking about our air defence strategy, as in, it has to be a layered defence. If you're an engineer designing something critical, for example, you would build in redundancies and backups, and then lubricate the hell out of everything. We have to do this with how we are going to design/build our tanks AND how we are going to use them.
If you've been watching the videos of Russians tanks getting fucked by FPV drones carrying mortars or thermite grenades or whatever, they are either all alone, or with very little support and no functional SHORAD in sight. As asymmetrical threats keep getting bigger, you simply can't do that, that type of use of tanks were a death sentence even in WW2, where almost 200k tanks and other variants were destroyed btw. And you also see that the tanks themselves have no way of defending themselves against these threats as well.
So, you start stacking your redundancies there. You put on as much and as good armour as you can without compromising mobility. Then, you add APS to deal with threats like a Javelin. Then the next step, imo, is a jammer against cheap FPV drones, soft kill is always a good option to have. Then you add some sort of CIWS, and when I say CIWS I do mean it. Whatever you put to protect a tank has to act like a CIWS on a ship and has to be able to detect, track and most preferably engage a threat by itself, with manual control as an option. Or, a system like Aselsan's 40mm grenade launcher anti-drone system. Especially if it can be modified to use something like Mete with guidance and proximity sensors etc. Yes, it would be expensive, but not as expensive as losing a tank.
But that's just the tank itself. We should never let a tank operate without proper support and aa protection. Obvious solution is, of course, systems like Korkut or Gürz working in tandem with our tanks and other support elements. A second solution, and one that multiple countries are actually working on, is as
@YeşilVatan suggested, UGVs. Imo, the important thing that is going to make it viable would be a degree of autonomy that would let the UGVs to be commanded, instead of controlled. So basically, let's say 2 UGVs with 20/25/30/35mm (pick one, don't be greedy lol) cannons, accompanying a tank, scanning the sky and engaging targets if necessary with little input from the commander. STM's Kargu already have this capability, STM and Roketsan's joint production Alpagut is going to have it as well. Auto-detects the target, informs the commander and if given a go ahead tracks and engages the target on its own. Or, can even be given free-hands to engage any target it detects in the area.
Armour has been a necessity since it was first used and it'll stay as one for a long time. We, and everyone else of course, simply have to adapt to new threats. Then after we do, a new threat will come up and the cycle will start once again.
