garage devs have told me of 10PiB+ deployments in production, but I've never operated one at that scale so I can't share much insight into the experience. Probably best to ask on t…

1. the article explains how many materials could potentially be sourced on the moon and provides potential magnet compositions to address that as well. 2. The moon weighs ~8.1 x 10…
