“That technology is not decisive in the carrier battle because you have to get within range not just to shoot but to shoot accurately, i.e., within ten miles.

You should read about Sunburn missiles.
The warheads come in around Mach 3.
The RIM 161 standard missile is Mach 10. CIWS is 4500 rounds per minute. You still have to launch the Sunburn from somewhere. Also, remember that a 500 pound bomb is not an automatic mission kill even if one or two missiles get through.
