I have shipped several thousand lines of code this week and I didn’t write any of it. I had a strong hand in its creation, explicitly asked for all of it, and it was integrated into a codebase of hundreds of thousands of lines which I did write. But I did not edit a file by hand. Complicated refactors, new patterns, frame-based layouts, all done exactly to my standard with minor cleanup required. I do not care how you feel about that and you now know it is possible.
