One possibility is that the BCI will allow powerful interaction of the sort simply not possible now based on using brain activations as supervision for understanding material in a way which transports those extremely complex abstractions into the computer in a software-understandable way: https://www.reddit.com/r/reinforcementlearning/comments/9pwy2f/wbe_and_drl_a_middle_way_of_imitation_learning/ https://www.reddit.com/r/reinforcementlearning/comments/9pwy... To give a quick random example: imagine the BCI records your global activations as you read that Reddit post about deep learning augmented by EEG/MRI/etc data; a year later while reading HN about something AI, you want to leave a comment & think to yourself 'what was that thing about using labels from brain imaging' which produces similar activations and the BCI immediately pulls up 10 hits in a sidebar, and you glance over and realize the top one is the post you were thinking of and you can immediately start rereading it. And then of course your brain activations could be decoded into a text summary for the comment which you can slightly edit and then post...
