If androids are originally artificially-made human-like entities, sort of robots, then we could consider the monster created by Herr Doktor Frankenstein one of the first ones, if not the very first, according to the wonderful story by Mary Shelley.
Human-like he was indeed, as he was made from dead human body parts her creator stole from cemeteries.
Alive thanks to science, once he was conscious of himself as a live being, the circumstances turned him against his creator and his closest friends, whom he ultimately ended up killing or contributing actively to their deaths.
Google, as a modern Doktor Frankenstein, has too created an Android. Still, Android per se has no sense by itself unless handset vendors use it and actually distribute it.
Open and free an operating system it is, Android can turn to a monster quite easily. And a dangerous one.
Watch out, hardware vendors on Android… some of you may not make it for the next version of the monster. By the way, isn’t it ironic that the Apple you wanted to compete against set already the example you might need to follow?
