Lots of new info a Singularity Hub here about the quest for brain / computer interfaces, which I think will be the next ‘really big thing’ on planet earth, in part because they’ll be cool and helpful and in part because they are very likely to speed up the creation of a conscious mechanical computer which will quickly surpass human abilities in all respects.
One of the odd things about following this science and these technologies is that about 90% of the world still thinks these are for the most part “kooky sci fi whacko” kinds of technologies and ideas, even as they become mainstream ideas in many tech circles.
