Git is the new code

As AI tools generate an increasing share of production code at companies like Spotify, Google, and Meta, the developer role is shifting from writing code to reviewing it. Data shows AI-heavy teams merge twice as many PRs but spend 91% more time reviewing them, with larger PRs, more incidents, and higher change failure rates. The post argues Git mastery is now the core developer skill and covers practical commands for this review-heavy workflow: undoing commits with reset/revert, recovering lost work via reflog, reading diffs efficiently, cherry-picking with --no-commit, advanced stash usage with named and partial stashes, bug hunting with bisect, parallel branch work using worktrees, and cleaning history with interactive rebase. It closes with a call for 'responsible reviewing' — understanding code deeply enough to explain and debug it, not just approving passing tests.
