They are rethinking the very nature of computers and are building machines that look more like the human brain, where a central brain stem oversees the nervous system and offloads particular tasks — like hearing and seeing — to the surrounding cortex.
New technologies are testing the limits of computer semiconductors. To deal with that, researchers have gone looking for ideas from nature.
