What is a Brain-computer Interface (BCI)?
 A brain-computer interface (BCI), brain-
machine interface (BMI), or neural prosthesis
is any technology linking the human brain to a
computer
 A computational system implanted in the brain that
allows a person to control a computer using only
brainwaves; e.g.; electrical signals from the brain

computer screen as…
 …the BCI registers the
electrical output of the brain
when the eyes are focused on
a particular place on the
computer screen

Philosophy of BCIs and DNA Nanotechnology
 BCIs: external aid or human and machine in
integrated synthesis and collaboration?
 What do BCIs mean for what it is to be human?
 Fundamentally not just human + tech tool
 24-7 connectivity means human cognitive processing
continuously linked to the Internet and other minds
 What is it if the human cannot not be online?
 Unavoidable bifurcation into different gradations
of improved and unimproved humans? (those
not augmenting with BCIs)
 BCI aesthetics inhibit adoption; need ‘Apple
design’ uplift to make BCIs beautiful

    April 2016 DNA Nanotechnology Philosophyof BCIs and DNA Nanotechnology  BCIs: external aid or human and machine in integrated synthesis and collaboration?  What do BCIs mean for what it is to be human?  Fundamentally not just human + tech tool  24-7 connectivity means human cognitive processing continuously linked to the Internet and other minds  What is it if the human cannot not be online?  Unavoidable bifurcation into different gradations of improved and unimproved humans? (those not augmenting with BCIs)  BCI aesthetics inhibit adoption; need ‘Apple design’ uplift to make BCIs beautiful 32
