Eons ago, I wrote a bash script to split up a test suite to run in different order across our device matrix, so even though the suite took hours to run, it took only 10 minutes to get an email that a test was failing on some machine.

I was gone in 6 months, but 3 years later the team (having doubled and doubled) still used that dumb script. Had they buckled down redo it in Java, they would have learned a lot and would have relevant experience to get jobs in the then-burgeoning enterprise server market.

Not bad for society, just for them.
