I'm not being flippant. If I need to sit and watch a claude session reviewing every edit it makes, that's slower than me coding the changes by hand. Either it's good enough to work independently or it's not worth using. I have no idea how Google is using AI, but from what I've seen at my own company I do know that using AI effectively _and_ setting up repos/projects for good AI usage (and with guardrails to keep AI in check) are both acquired skills. Skills that the majority of devs don't have right now.
