Idk, my mate who's mind was shredded by failed psych treatments almost got one till I talked him down. He was optimistic about an interface that could be easier to use with shot working memory and maybe help him remember all the stuff he forgets.

I don't know why you have to be so contemptuous of people. What's the gain? how does anyone's life get better by being scornful of people who believed lies for the few moments it took to impulse purchase something? What's the point of that ideology?
