I do feel my thinking about computer puzzles gets stuck when I have no one to talk to, but the $$ AI Chatbots simulate conversation enough to unstick me. Today I got them to carry me as far forward as noticing I can easily tell a shell to poll for an answer, and tell me every time the answer changes. The conventional way to do this in Linux erases all but the last answer, which has frustrated me at least since late Nov/2015 when first I came back into working with Linux & macOS. It is easy to rebuild enough of the conventional logic to fix just this one broken bit, but all the same somehow I had never got that far forward before today. I’d say what I was stuck on was a lack of conversation.
