About 16 days after my last update I took a full time job. So here I am at age 69 working my tail off for “sweat equity”, which means that I am not getting paid.
So: The simulation project is on hold until I retire again. Could be a few years. Everything will change in a few years: computers, languages, state of the art in Artificial Intelligence, state of the art in Behavior Analysis, and so on.
The reality is that I may never get back to the simulation project. On the other hand, when I do retire again, maybe I will be better off financially and be able to make faster progress.
But of course, I am old. My retirement may come as a pile of ashes!
