This is an important question for software development in general. I find it interesting to see just how much simple tasks (say parsing data and combining it with other data) results in significant improvements in user experience.

I am not in the "everyone should learn to code" camp, but I sometimes think that everyone should know a few standard Unix command line tools.

Maybe the link between effort and economic gain will balance back out sometime. Maybe right now is just one of those boom times in history and useful tool creators are in position to reap the benefits.
