AI Made Me a Better Reviewer (The Hard Way)

I build a SaaS QA platform. When AI coding assistants became good enough to trust with real work, I leaned in - and my velocity went up noticeably. Less boilerplate, faster feature implementation, fewer rabbit holes on syntax I'd forgotten. But something shifted that I didn't expect. I wasn't writing less code and saving time. I was writing less code and reviewing instead. For a while I thought that was fine. Then one evening I pushed a feature involving Google SSO and suddenly users couldn't log in.
