What is the central idea of this passage:
"Many people use the words cyborg and android interchangeably when, in fact, they have
different meanings. Both terms refer to beings powered by robotics, but an android is powered
entirely by robots. Though androids are completely mechanical, they are designed to look like
humans. They may have synthetic skin, hair, and other features, but no human organs. On the
other hand, cyborgs are part human and part machine. They may have robotic hands, legs, or
eyes, but all cyborgs have surgically implanted technologies that enhance their abilities."
Androids and robots are different things.
