No I didn't Magnus, but ... What a (biological) brain "is" (excluding it's mind / thoughts) is a level 1 & 2 pattern. Ie it's alive, it's made of meat and chemicals, and those are a physical pattern, but the things it's made of replace / heal themselves and reproduce themselves, hence alive.
It is seems conceivable for a physical (level 1) non-biological brain to exist. The question is that in order it to be complex and robust enough, it "might" also need to be alive first. ie I'm frankly not sure if strong-AI can exist without artificial (non-bio) life first. So good question Magnus - a for a physical machine (level 1) to be a thinking (level 3) brain, it may also have to exhibit level 2 patterns first. (I was really responding to the weaker-AI ideas where people see calculators, memory devices and computers as a kind of non-thinking "brain" - an oxymoron.) Ian.
