Incentives dominate intentions.

We focus on intentions because we can see them more and our brains are tuned to people, not systems.

But what matters is the outcome and the incentives influence that much more.

Over time everything falls down the gravity well of its incentives.

Each incremental move is individually fine, but makes it easier to take the next one, which leads to a compounding rate of movement towards the incentives.

That's why you need "can't be evil" not "won't be evil".

Lash yourself to the mast.
