It can be very easy to deduce this hypothesis. I remember when I was young and we were studying the functions of the brain and cogisence. It dealt with how we are able to find our way around. It deals with seeing familiar items and registering that in our brain. It was all very mechanical and distressed me greatly. However we are sentiant. Which means we are aware of our existence and our mortatlity. That would make us more like an android. Robots only respond to commands given to it. They do not think or rationalize. In a sense we ARE biological androids reacting to the stimuli around in a manor we are taught (programed)
Yes, I have thought along similar lines as well and that's why I like to ponder upon these things. :)
