author here. didn't expect our paper to appear on HN :) But regarding: "Am I only one who thinks that we will be able to simulate the brain with much less computational power than the brain itself has?" - I really doubt that. In fact my bet is that we won't. If anything our learning approaches looks much more inefficient (data-wise) compared to what brain can do. - And the paper doesn't study this question. It is a focused study on speed/accuracy tradeoff for LSTM cells
