Drones have a limited range and limited capacity to inflict damage. Yes, they are effective at hunting infantry, but you can't reach across an ocean and strike the US with "millions of drones".

Relatedly, aircraft carriers are great for beating up on small powers, but they are vulnerable and would not be effective at reaching across the ocean and bombing China.

Plus, both nations have nukes, so the idea of either China or the US "winning" a war against the other side is easily cancelled out.

What you are left with, is a lot of posturing about superpower wars which is a waste of time. All sort of people thumping their chest, wargaming things out, as if any of this nonsense isn't immediately squashed with the nuclear trump card.

There will be no superpower wars.

There will, however, continue to be wars against smaller states, and the F35, aircraft carriers, etc, are really effective at those kinds of things. That is, effective at waging the wars that will actually happen. Nukes and the pacific ocean stop any war of consequence against China.
