Is it good to continue working on these kinds of technologies? Unequivocally yes it is. It will allow us to gain a better understanding of how the brain functions and this increase in basic understanding can serve as the frame work for helping people with psychological diseases, perhaps neurological diseases. The pathways of the brain may seem pretty well mapped out, but in reality that map is pretty damn smudgy. I think technologies like this will prove to be a huge net benefit in the long term.
