You're really missing the point. Have you ever even been on a boat? The Pacific Ocean is a big place, and carriers don't move in predictable straight lines. Drones aren't going to be able to loiter in place indefinitely just on the hope that a carrier might wander into range.

The Chinese are not stupid. Their A2/AD doctrine is based on large, expensive manned aircraft and fast missiles, not slow and weak little "drones".
