My answer is I would. I enjoy the process and at this point, is my most reliable way to the flow state. I am more motivated by the process and the learning of making than I am about finished products.
I have a couple of projects that I day dream about but are an unrealistic size for me while working:
1. Turning my emacs configuration into a electron app is a project that nobody needs but I want to build.
2. As much as I can, bring a lisp REPL experience to the python world. (or maybe I could just use clojure for the other projects.)
3. Apps and software for accessibility (including tools for the neurodivergent)
And I'd continue to spend time prototyping software to learn how it works and building developer tools.
Curious about other's choices, what would you choose?
