I increasingly feel that almost every business would benefit from having someone with programming experience on-board. This comes from observing that businesses tend to have a lot of ad-hoc processes and unique requirements, for which there is no software package to buy - not without throwing away huge parts of the processes and rebuilding them in a "standard" way. However, a lot of those unique areas could be improved with a help of someone who's capable of writing small programs and scripts to glue things together.

A random example: my SO often works with high-res photos of their products, and sometimes this involves modifying them to suit the random requirements of other businesses. Something I currently solve for her by running ImageMagick one-liners if she needs more than a few photos modified. A person with basic familiarity of shell scripting and CLI tools could improve their workflow and keep improving it on-demand, as the requirements change.
