Re: Do androids wet dream of electric sheep?
They were wet-ware with wipe-dates, no silicon involved.
This is correct, but of course testing for this special makeup physically would have been easy-peasy. A drop of blood and check the DNA. Done! (Like the Gaius Baltar test which was not handled all to well in BSG at all).
The Philip K Dick novel's androids appear to have been a mix of robotic and organic bits.
Not that I know. They were, however, devoid of natural human reactions and empathy (psychopathic) and killing them was considered taking out the trash. Even Rachel was the most horribly sadistic and manipulative thing.
