No not really. Barring concrete physiological evidence, innateness is simply an unfalsifiable position. I do think you can say that consensus among scientists might have shifted against innateness, but that is definitely not because of some computational model such as RNN with some passing resemblance to observed behavior of human neurons. The way these networks are configured and trained has nothing to do with real brains, nor does the abstraction in neural nets leave room for any electrochemical effects.

Is it? A neural network can achieve that by simulating a Turing machine or simpler automaton. I don't see what that brings to the table? That's just doing something we could already do, but less efficiently. I think the interesting thing is the opposite: if the RNN can do something which couldn't be done before with other models.
- YeGoblynQueenne 11y agoDammit, why do I always get carried away discussing details and forget the main point? That, what you say- that's the business. An RNN (any ANN) is not a human brain. It is one model of the human brain, based on our very limited understanding of human brains. It doesn't matter what ANNs can and cannot do, how well or bad they perform, it tells us nothing much about how we do language; or vision, motion, decision-making, anything.
- andreasvc 11y ago> It is one model of the human brain No it isn't. It's loosely inspired, but the goal is to make something that works, not to simulate what we know of the human brain. There's a different field, computational neuroscience, which does try to make faithful models of the human brain.
