Why should we care for some crystalline beasts? We don't desire to modify lions to eat vegetables

I do. Pain is painful in "beasts" too. What does it matter if they are made of crystals, are hairy or whatever?

The anthropic principle strikes me as being largely too clever for its own good, at least, the people who think you can sort a list in linear time by randomizing the list, checking if it's sorted, and if it's not, destroying the world.

Maybe it's stupid and evil, but what stops it from actually working?
