Great advice, my SO works outdoors doing field studies and the amount of shit they talk about doing manually is astounding. They pay people (or sometimes unpaid interns) to go through hours of videos documenting everything they see! Almost all cataloging and measurements are done with little to no technology. Another example; I volunteer for a program that does some human intake and processing, before I got there everyone used a series of paper forms that got updated by work of mouth. Now? Google Spreadsheets.
There's hundreds of industries, organizations, and groups that do extremely manual labor intensive work because it hasn't even occurred to them it can be automated or turned in to a service, but you'll never meet them if you hang around tech people all the time because the solution is always on their mind.
