Random circuits are really only good for proving that you are in fact operating a quantum computer, since you can test the results, and random quantum circuits can not be efficiently simulated by classical computers. So quantum volume is not a totally meaningless metric, but it doesn’t necessarily indicate any capability for real problems that people would like to use quantum computers on: factoring, solving discrete logs, general search problems, or simulating quantum physics systems.
