Why Brain-to-Brain Communication Is No Longer Unthinkable

This from the Smithsonian.

For all that science has studied and mapped the brain in recent decades, the mind remains a black box. A famous 1974 essay by the philosopher Thomas Nagel asked, “What Is It Like to Be a Bat?” and concluded that we will never know; another consciousness—another person’s, let alone a member of another species—can never be comprehended or accessed. For Rao and a few others to open that door a tiny crack, then, is a notable achievement, even if the work has mostly underscored how big a challenge it is, both conceptually and technologically.
