Thanks to this response I now realized that we have similar backgrounds. I retired from software development in 1995 at age 49. I’m still writing code and leaning new things 20+ years later. Last year I gave Smalltalk (Dolpin) a shot, based on your recommendations. My old brain just isn’t up to dealing with the paradigm shift. I’ve returned to Go, and am really enjoying it.
One difference is that my pro-bono work is limited to political ranting. I like your choice better!
