Description

Distribution
gollark: I don't think this is true, except in a very broadly defined sense.
gollark: If *evolution*... well, "attempts" would be anthropomorphizing it... to cross said chasm, all it can do is just throw broken ones at it repeatedly with no understanding, and select for better ones until one actually sticks.
gollark: If I want to cross a chasm with a bridge, or something, I can draw on my limited knowledge of physics and materials science and whatever and put together a somewhat sensible prototype, then make inferences from what happens to it, and get something working out.
gollark: No. We can reason about problems in various ways. So can some animals.
gollark: It doesn't have its own will. It's a giant non-agent mess driven by tons of interacting blind optimization processes.
