I would expand on this and make a suggestion to people who write software. Use the computing lever, please. Computers are insanely fast and getting faster. If there is a task that you can perform automatically, do it — don't bother me.

Case in point: almost all OCR software is deeply rooted in the 90's when processing power was a fraction of what it is today. Therefore, you load a scanned book into an OCR program, click "Recognize", the program spends 30 seconds doing its work and happily says "I'm done!", while you are left with 600 errors to correct manually. I'd much rather leave the program running for several hours (overnight!) and get 6 errors to correct manually. There is often a tradeoff that many fail to think of.
