[Satan]

I understand your point that we as humans don't understand our own biology and that it would be impossible at this point in time to teach it to an artificial intelligence. But some time in the future who knows what we can accomplish.

The problem is that once people understand what makes them human, and trying to copy it, it will go the way of cloning, likely, long before and progress is made. Individuals with the power of those decisions don't like the idea of people playing god.

Not to mention, once something else becomes like us, what defines us as human anymore?
