One of the depressing features of the 2008 financial crisis was the great number of industry titans who went smoothly from "My awesome insight is worth tens or hundreds of millions annually" to "Who could possibly have known?"

I would hate to see the same thing happen again when algorithms fail to work as hoped. If people build and deploy a system, they should be socially and legally responsible for its effects in the world. And executives should be held responsible by the rest of us. I'd like us to be done with the shrug-emoji-and-cash-the-bonus-check school of corporate governance.
