Those cheap drones and missiles are only effective against relatively soft, static targets. As I already explained above, manned aircraft are still the only platforms capable of executing critical missions in complex, dynamic environments. Maybe that will change in a few years but not today.

Ukraine and Russia are both second-rate powers making do with what they can manage because they're too poor to afford anything better. The systems that sort of work in Eastern Europe likely won't be effective in a major conflict between the USA and China around the First Island Chain. (Let's hope we don't have to find out for sure.)
