Folks, my answer to one question: how can you define "human".
I believe that was our memories. Our memories define who we are and what we are. Without it, I don't know how we can define who we are... For example, as you know that I am a ultra liberal and can be very blunt & asshole (well, I never want to be a asshole but my bluntness can get someone to think or assume that I am a asshole so I am not surprise 
) in some point. How do you guys know that? Based on your memories, right? Without your memories, how can you define me?
We know that Vamproxy is a funny guy...how do we know? based on our memories, he shared his sense of humor with us in the past and we 'stored' that part in our memories. That's how we define Vamproxy as a funny guy (and of course, more). I know that Banjo is a canadian because he mentioned it to me a while ago and I 'stored' it in my memories and I started to define him as a canadian and movie lover based on my memories.
Right now, scientists are in hot debate about clone. Some scientists state that clones that cloned from us cannot carry our memories because it is 'fixed' to our original body & brain. Some scientists argued that it can be carry to clone(s) because it is automatically integrating into our genes... Which one is right? We still don't know. That's why I believe that memories itself can define "human" as it is.
But I cannot answer this question, what does it mean to be human. I still couldn't... If we are going to discuss about our abilities & human qualities then I believe that animals are more 'human' than we do.
Edit: Animals & robots do have its own personalities, so we cannot use that as well...
