But that's not how Richard responded. He literally restated the problem in different terminology, replacing the problems with black boxes that have the solution inside

I was being flippant. I mean, what were you expecting? Imagine that the person who first had the idea that thinking is done by neurons has just published it, and you ask them what you asked me. What can he tell you about finding a girlfriend? Only that it's done by neurons. The leg work to discover just how those neurons are organised to do it is the problem, and finding a mate isn't the place to start, experiments like Hubel and Wiesel's on cat vision are the place to start, or mapping the nervous system of C. elegans.

Likewise, I'm not passing off "it's done by control systems" as the solution of a problem, but as a basic insight that gives the beginning of a way to study living organisms. The place to begin that study and establish exactly what control systems are present and how they work is in studies like the one that you dismissed as a trivial game.

That's what real work looks like. Have a spade. A start has been made at the various PCT links I've posted. Maybe in 50 years you'll get an answer. But don't be downhearted -- it's been more than a century so far for "it's made of neurons".
