Two systems that produce the same output for some set of inputs doesn't show the systems are the same. My phone can produce the same results as my brain for short arithmetic problems. My phone is not a brain.

The neuroscientists I know in the field would be among the first to tell you that our ability to model the brain is nearly non existent. In fact we don't even have a great model of a single neuron [1]. This statement doesn't invalidate the work folks are doing to try and reach that goal. Biology is hard.

As a working neuroscientist, I’ll co-sign this!

Understanding 50% of the brain, whatever that would even mean, is an utter fantasy.

I should have clarified that I was talking about the specific brain function of semantic comprehension.

I am not suggesting that we are anywhere near having a complete analytical model of 50% of the brain.

I am suggesting that we do have tools to continue answering questions about functional aspects of the brain.

Or am I missing something that indicates the non-utility of “function analysis” of biology-based artificial neural networks?
