Imagine programming one for the sole purpose of feeling lonely.
First of all, loneliness is a mindset and a choice. There's different kinds of loneliness.
Wanting a (sex)partner, wanting a genuine friend, existential 'lonely' thoughts, thoughts that nobody loves or cares for you, wanting a deceased person to be alive and have good times with, and more.

So when people say they feel lonely they actually mean they're having thoughts and want a boost of hormones which will make their body feel better unconsciously? And their mind? The desire to have a connection with someone will no longer be craved? Having lonely thoughts makes them feel sad? But that brings me to another issue, feeling sad is also a choice. What about feeling happy and would a person even think that they're feeling happy most of the time. Something definitely chemical is going on when a person is in a happy or sad mood. Someone's mood or thoughts are most of the time neutral though?

I don't understand how people can feel lonely. I'm even having trouble with understanding what the word 'feel' even means (not as in touch). How would you program a robot to feel in it's conscious mind? Is consciousness computational? Almost every language in the world has a word for 'feel' right? Are there any languages who don't have it? In German for example, they have tons of words that are not in English. For example a german word for you "feel" alone in the woods.

Someone want to share their view on this?
