“While a number of people have pointed out the various costs and drawbacks of sentience, few if any have taken the next step and wondered out loud if the whole damn thing isn't more trouble than it's worth. Of course it is, people assume; otherwise natural selection would have weeded it out long ago. And they're probably right. I hope they are. "Blindsight" is a thought experiment, a game of "Just suppose" and "What if". Nothing more.

On the other hand, the dodos and the Steller sea cows could have used exactly the same argument to prove their own superioirity, a thousand years ago: "if we're so unfit, why haven't we gone extinct?" Why? Because natural selection takes time, and luck plays a role. The biggest boys on the block at any given time aren't necessarily the fittest, or the most efficient, and the game isn't over. The game is never over; there's no finish line this side of heat death. And so, neither can there be any winners. There are only those who haven't yet lost.”
