Why are we here?

The main reason people are here on Wrong is resources. People (human and non-human) have become very efficient at extracting minerals from comets and planetesimals. Wrong's system, by some quirk of solar system evolution, has a small, sparse cometary belt with few exploitable resources. Wrong, on the other hand, is rich in iron, copper, gold, nickel, potash, and mineral sands, and many of the deposits are available for both economic and sustainable mining.
