I think we'll learn a lot about chip implants when Professor War-borg does
his next experiment early next year. If I understood it correctly, this
time he is going to determine if the afferent connections work well enough
to upload significant amounts of information directly from chip to
brain. Anyay, the article is in Wired, Feb/01.
