Would it not be preferable to launch drones from less of a big target? The issue is that the carrier is clearly visible and targetable. You could go submersible or just spam much smaller ships with smaller payloads. In those cases you get the benefits of the same level of assault without the potential of a hugely expensive loss.
At a guess, I assume much of the scale of carriers is tied to the logistics of air power, which are considerably less relevant in drone warfare. Carriers will always remain useful for more accurate strikes and operating aircraft that work at higher altitudes, but this broadside idea of volume might work better on a platform that scales better instead of the huge and expensive carrier footprint.
