Artificial Neural Networks: Man vs Machine?

Are these hubots something human or some kind of machine? If Human intelligence can quickly tell the difference between the two, machine learning must rely on algorithms like artificial neural networks to make a prediction. Patterned after the structure of the human mind, do ANNs allow machines to think like humans? What exactly are ANNs, how do they work, how do they differ from other machine learning algorithms, and what are their use scenarios in data science? Computers were originally designed around algorithms composed of predetermined steps to calculate the right answer for a given case.
