It is conceptually the same thing. […] The learning the part is not even close.
Well… isn’t the “learning part” precisely the point? I don’t think anybody is excited about brains as “just” a computational device, rather the primary function of a brain is … learning.
Sorry then if I sound like a broken record but again, doesn’t that mean that the analogy itself is flawed? If the goal remain the same but there is close to no explanatory power, even if we do get pragmatically useful result (i.e. it “works” in some useful cases) it’s basically “just” inspiration, which is nice but is basically branding more than anything else.
