Human "Robots" I don't think your concept of human robots is possible or realistic in this world. All living beings have consciousness. Animals have consciousness. Therefore humans have consciousness. I don't understand what you mean by devoid of consciousness. I have consciousness, or else I wouldn't have thought to come here and find this and think of a reply. Any human being can do that if they wanted to. Unless they can't read yet or have a disability that prevents them from being able to, but not knowing how to read or having a disability doesn't take away the fact that the human is conscious.
The argument for being drunk is a curveball but unconsciousness doesn't make one a robot. Just as everyone has consciousness, everyone has unconsciousness. The unconscious mind is full of all the information that a person is not conscious of, for example, their drunken stupor or sleepwalking. Just because they don't know they're sleepwalking doesn't mean they're a robot. There's no rational or logical programming to make someone sleepwalk. It's just a symptom of a mental disorder. Plenty of people have mental disorders that lead to all kinds of symptomatic behavior but they're not robots. They're alive and they have individuality.
Working and learning and studying does not make one a robot. I do those things. I do repetitive tasks in a factory with conveyor belts, doing the same thing all day without getting tired or breaking a sweat or getting bored. Still, that does not make me a robot. It means I have very high amounts of stamina, patience, strength, fortitude, and motivation. I can focus on a task and do it for 10 hours because I enjoy doing it. I'm still a consciousness, a human being, not some artificial intelligence. I also spend hours reading, learning, watching philosophy lectures, meditating, and self reflecting. That doesn't make me any less human.
So I would like more elaboration on why you believe humans who do hard things and learn about nature, reality and inventions are robots without consciousness. These ideas don't make sense to me without more context and clarification. Learning and working are things every animal and human does. All of those things are conscious. If I know I am conscious and everyone on this forum including you are conscious, what makes a person devoid of consciousness? What do you constitute as a "real" human? Because I think of the 7 billion plus humans on earth, all of them are equally as real as you and me. So what constitutes a "fake" human? Why does working and learning detract realness?
