I saved enough to live comfortably -not richly.
I spend almost all my time, writing code for free. My GH Activity Graph is almost solid green. I'm working on releasing my sixth or seventh free app in just a few years (almost all are open-source). Over the last dozen years, or so, I've released over 20 (most are deprecated).
I really don't look forward to having others destroy my work, anymore. After a fairly brief time, looking for work (at age 55), I quickly figured out that, even if anyone hired me, they would treat me (and, even worse, my work) like crap. They certainly did, during the hazi- er, interviewing process.
So I guess I'm one of those "disincentivized to work" folks.
