Fast feedback is no longer straightforwardly good: agent-speed loops make you rebuild your mental model dozens of times in half an hour.

Nicole Forsgren Researcher of software delivery performance There were a handful of people probably managing a security review process or a launch process or a deployment process or, you know, sometimes reviews were a little slow and they got backed up. Well, now we just threw gas on the fire and so all of that is a problem.
