<i>Part of the reason for using a swarm is rather than just one Arkyd is, counter-intuitively, the cost. “The key is redundancy and safety in numbers. We’re planning for a certain amount of failure, and it’s a lot cheaper to work for 80% reliability than it is for 99.9% reliability.”</i><p>This is going to be the killer [NPI] feature of using automated rather than manned systems. Aiming for just-reliable-enough + spares, rather than Failure Is Not An Option is going to impact just about every single part of it, and reduce costs massively.
