N. Alexander, writing at the Off-guardian.org, far superior material in my opinion to the Leftist, The Guardian, has given a thoughtful discussion of the philosophy and ethics of AI-based mind-reading. He makes the case that there is no real socially advantageous reason for this technology, even for paralysed people as there is already surgery-free interfaces, as was used by Professor Stephen Hawking. Alexander gives a long and detailed argument along those lines, that these technological developments are not in the interests of the ordinary people, that there are few crumbs tht will fall from the table of the elite technocrats. What is being done is to push these developments, usually funded by the long-suffering taxpayers, which will deliver social control that will be of sci fi dystopian levels.
