> What software would you write if you could write whatever you wanted using whatever language/technology you wanted?
The sort that solves problems I'm interested in. I love the idea of treating software as a home-cooked meal [1]: something you prepare with love for a small crowd of people.
For instance, I added a recipes section to my personal website. I also added achievements to it some time ago[2]. Both were completely pointless, but I enjoyed doing it the same way I enjoy cooking.
