Why Bitcoin?  Why do people use Bitcoin?

People seeking privacy in their financial transactions-- for legitimate or illegitimate reasons -- might also use Bitcoin because it's more anonymous that financial transactions using credit or debit cards.

Artificial Intelligence or AI

AI is the broad branch of computer science. The goal of AI is to create systems that can function intelligently and independently. Humans can speak and listen to communicate through language. This is the field of speech recognition. Much of speech recognition is statistically based hence it's called statistical learning. Humans can write and read a text in a language.  Humans can see with their eyes and process what they see.  Humans recognize the scene around them through their eyes which create images of that world. AI ( pronounced AYE-EYE ) was coined by John McCarthy , an American computer scientist, in 1956 at The Dartmouth Conference. According to John McCarthy, it is “ The science and engineering of making intelligent machines, especially intelligent computer programs ”. Artificial intelligence is the simulation of human intelligence processes by machines, especially computer systems or you can say "  Artificial Intelligence (AI)  is the scienc...
