This quote has an unintended amusing aspect, and that aspect might reflect on unexamined assumptions of the natural sciences. I say this because you HAVE a brain machine interface whenever you pick up a hammer, hit something with a hammer, or invent a new kind of hammer. That is brain machine interfacing. Still we all understand the use in the article excerpt above, of the phrase "brain machine interface." We understand the writer means to convey the goal of a bodyless brain machine interface.
We understand possibly because we share this unexamined dream of the mind as separate from the body, that so-called mind body dualism, even though there is no evidence to support it. Yet the scientists dream.
