But before AI it was possible to keep things in check because pull requests were manageable in both size and frequency. Now we have people passing figma screen shots to copilot and Claude and putting up single shot pull requests that have what used to be 5 jira stories all in one. It's impossible to keep any semblance of consistency and correctness in the codebase. Its also exhausting for the people that actually care.
The Pull Requests were maybe manageable, but the backlog wasn't ;). AI does help with that. And the tools that require more stability you can still spend more time on and review the code.
