How does one articulate “conscience” or “intelligence” or an opinion? I think these are all a product of circumstances/luck/environment/slight genetic differences (better cognition, or hearing or sight, or some other sense brain, genes could define different abilities to model knowledge - such as backtracking etc).
So to get a “true” human like opinionated personality, we’ll need to restrict its learnings to that of one human. Better yet, give it the tools to learn on its own and let it free inside a sandbox of knowledge.
