Part of a broader pattern in military technology right now. All weapon systems that consist of an expensive vehicle and an expensive-to-train crew are being re-evaluated against drones right now. If you're fighting a highly asymmetric conflict where your enemies can barely touch your expensive toys then it's less of a concern. If you're fighting near-peer it's a different story.
It's not a new discussion, this comes up every decade or so when some new technology takes expensive kit out but just as with the tank nothing is going anywhere.
Paraphrasing I can't remember who, "if you're getting out of the tank, what are you getting into?" Helicopters, tanks, mechanized and combined arms warfare and metal are still pretty much the only way you take territory, there's no alternative, even if drones start taking helicopters or expensive vehicles out it's the only thing that is mobile and packs a punch and protects your infantry.
