how many atheists don't think humans are just robots?

Are you claiming that anything other than complete unconcious existence after death means "magical afterlife"? If it's something that science doesn't (at the moment) touch a concious afterlife, it would have to be magic?

It's not unconscious

existence. It's not existing anymore. Are you proposing that there IS a magical afterlife? Cool, what evidence can I examine to determine it's definitely there, as you have? Yeah, I'm calling it magic. 

We're sort of back where we started: how did you arrive at this opinion? Because it sounds like nonsense. 

That isn't actually the question of the book Frankenstein's Monster. The question in that book is if you did it, what do you owe to it? For example, if you

could create sentient life, would it be moral to create it with the full knowledge that you were going to torture it for a really long time just for your own amusement? Would you owe it free will, the ability to love? What would it owe you, would it be moral to keep it as a slave? Would it have to do as you bid under fear of bodily punishment? 

??????? This is word salad. I'm glad to address if you can clarify what you're trying to get at. What's it have to do with sentience? 

Is it immoral to intentionally bring a child into a cruel and hostile world?

In the late 1950s, a Russian geneticist called Dmitry K. Belyaev attempted to create a tame fox population.

If the cubs continued to show aggressive or evasive responses, even after significant human contact, they were discarded from the population – meaning they were made into fur coats. In each selection, less than 10% of tame individuals were used as parents of the next generation.

By 2005-2006, almost all the foxes were playful, friendly and behaving like domestic dogs. The foxes could "read" human cues and respond correctly to gestures or glances. The vocalisations they made were different to wild foxes.

"The main surprise was that, together with changing of behaviour, many new morphological traits in tame foxes start to appear from the first steps of selection," said Trut.

The domesticated foxes had floppier, drooping ears, which are found in other domestic animals such as dogs, cats, pigs, horses and goats. Curlier tails – also found in dogs and pigs – were also recorded. [LINK]

In other words, selecting against aggressiveness incidentally made the foxes look like dogs.

Or an alternate theory might be that while we were selecting against aggressiveness in foxes, Jesus figured out what we were looking for, then decided to make foxes look like dogs, meaning that our efforts to do all that genetic engineering weren't ACTUALLY working, they just looked like they were working, but were actually responding to divine intervention. Feasible?

How do you know the brain isn't just a filter? 

but sometimes the sheer coldheartedness of these experiments just really gets to me.

why isn't there random hallucinations at death? why isn't t here imagery of getting abducted by aliens? or something like an acid trip? why is it that there's a coherent and very vivid death story, in some version or another? 

but sometimes the sheer coldheartedness of these experiments just really gets to me.

It's clearly impossible to study the effects of oxytocin on behaviour other than by using live animals.

I'd say lab animals are better off than many animals raised for meat and much better off than battery hens.  Cold-hearted is a bit harsh.  Certainly animal researchers have to very objective in their experimental designs to achieve good results, but I think few are 'cold-hearted' in the sense of being indifferent to any suffering they cause.

There's not much danger of an AI being sentient in the forseeable future because AIs (such as alpha-go) work by evaluating a 'decision tree'.   Essentially they use brute force and rely on raw speed.   Current AIs don't know what they are doing nor why they are doing it.   Current AI is a great way to make a task-focused robot, but not to make a sentient one.

It's  impossible to answer those questions unless someone can work out how to nearly kill people in lab conditions!
