computation is boolean algebra.
-> therefore, doing math is to think.
I'm not trying to be pedantic, I just don't think using intuitive associations with words helps clarifying things. If your definition for thought diverges here, please try to specify how exactly: what is thought, then? Semi-autonomous "pondering"? Because the closer I look at it, that, too, becomes boolean algebra, calling eval() on some semantic construct, which boils down to symbolic logic.
What you may mean is that "neural" networks are performing statistics instead of algebra, but that's not what the article is about, is it?
