Technological singularity is the hypothetical point when artificial intelligence becomes sentient, smarter than us. When it can start improving itself.
We humans are sentient beings from the start. It doesn't take long to become self aware. We naturally learn lots of things. Then we go to school where we are teached more things. But for the most that's about it. We take what we have learned and live the rest of our lives with that. With the skills and talents we have acquired.
As with the machines the key point is the improvement. When we realize we too are capable of improving ourself thats the point I call humane singularity. For us it's not as easy as machines as we just can't rewrite our code or upgrade our hardware. But still, we can improve.
Just realizing that idea can be the turning point. Knowing that you can become what ever you want to be if you are ready to commit doing whatever it takes. With practice and determination you can reach anything. At least anything that is within the capacity of human body.
There are no superhumans. Just people who have decided what they want to be and committed entirely to that goal.
