That's right. Thank you for the question. You've got it exactly, which is that we want engineers themselves to be knowledgeable and accountable for the products they create.
In addition to that, though--and this is important--we are building additional checks and balances into the system, so that even if somebody makes a mistake or an error in judgment, that doesn't percolate all the way through to launch.
There were opportunities for this to be caught, but we want to build more opportunities, deeper opportunities. Included in the changes that we've announced, for example, are compliance audits, where there will be teams at Google whose job it is to audit the products that teams create to ensure that the actual thing that's happening is what's in the product design documents.
