I have finally found out that the so called AI Machine Vision is actually HI (Human Intelligence) or Human Vision.
Those big tech companies outsource huge tasks of identifying and tagging visual objects in real world to "blood & sweat" software factories which in turn hire huge amount of human labours to tag objects in our everyday living. It goes without saying that wages of labours in "blood & sweat" factories are super low.
It is the whole background of the so called autonomous driving or Machine Vision.
Then, we add the good old scientific core of Cybernetics and Control System Engineering, we will have a so called autonomous vehicle.
