The concept of what a normal human should be is really mind boggling. What kind of personality is a normal one? What kind of motivations or life goals are normal ones? Is it even normal to have a motivation or a life goal? Should a normal human have a few health defects? What is a normal person's intelligence level and how can it be quantified? What kind of feelings should a normal human experience? How should a normal human react in certain scenarios?
These are all questions that no human can answer due to the limits of their current technological developments.
I'm very open to opinions on this topic.
