>> It will happily recreate the same function in several different places for no reason

So do many developers. I've lost count how many times a code review had to be rejected or cleaned up because of copy and pasted code and I'm going to admit, sometimes it's just quicker to duplicate a little code and leave a comment for 'next time'.. we've all done it.

.. like this one time I had a PR and the developer created on loooong linear method, couldn't figure out how to share between targets and copied and pasted the same bad code somewhere else. Somehow it got through and when asked why this was on production the answer was 'it worked'.

>> no time for elegance

This happens, your experience in is generally your quality out. But that doesn't necessarily mean there's going to be elegance. I've worked at major product driven companies where elegance took a back seat to getting release out the door.
