Those questions are moot. There are situations where it's simply impossible to have a human in the loop because reaction time is too slow or the environment is too dangerous or communication links are unreliable. Russia is deploying fully autonomous weapons to attack Ukraine today and they will be selling those weapons (or licensing the technology) to their allies. There is no option to stop.
