Machine Learning: An Artificial Intelligence approach

I've heard a lot of people saying that Machine Learning is nothing else than a synonymous of Artificial Intelligence but that's not true at all. The reality is that Machine Learning is just one approach to AI (in fact it's called the statistic approach). Let me first give a definition of Machine Learning. It's a type of artificial intelligence that gives computers the ability to learn to do stuff via different algorithms. On the other hand Artificial Intelligence is used to develop computer programs that perform tasks that are normally performed by human by giving machines (robots) the ability to seem like they have human intelligence.
