I'm not learning it to get a job. I'm actually building a file manager/database for my wife's Cricut images. I found building desktop app/UI's was fun again. I hadn't built a desktop app in a long while, last one was Java Swing. After using it for a bit I figured it might be a nice niche tool set or skill to get good at to find a better place to work. It's a tough choice doing what you like (building an app) or learning algorithms - one is more enjoyable than the other.
