Thankyou for adding what you understand about the term. I agree with you that it seems to be a sort of techno-jargon, used to establish and maintain an illusion of knowledge. I'll look it up. I did the first year of a computing degree before changing to philosophy and can't remember nodes being mentioned. Top-down programming yes, nodes no. It was about 1992.
So I mentioned the idea of approaching your son.
Who you've touted many times here - and mentioned conversations about on this subject.
Should I indulge your obsession with credentials by reminding you that he 'knows much more than you' ?
Again - 'nodes' here isn't about credentials nor knowledge levels.
Nor about 'you and me'.
Its about a particular person using the term to defeat a much more realistic conversation about daunting computer projects in chess that would likely occur if the true technical speeds of computers involved was openly factored into the conversations.
One day i think it might be solved but can still be played by humans
