People often cite this cartoon by Randall Munroe to point out that automation doesn’t always save time.
But automation is just as much about consistency and accuracy as it is about time. I feel more confident in my corrected directions because they were done by a script instead of by hand.
I’ve said this at work too… I write tools to do my job, especially mundane tasks, because I inevitably screw it up. If I can teach a computer to do it once, it’s repeatable.
(I do smooth out the curve a bit… for one report I make I have an excel book that I can cut and paste the contents of an automatically generated CSV into. The tradeoff here is that I didn’t write Python that could edit the original excel workbook)
