At its core Artificial Intelligence is about teaching computers to do what humans can do with the expectation that computers will do those things better. Examining the history of technological progress it is possible you will not live long enough to see Artificial Intelligence change the world. Assuming AI is something that will change the world and that is in no way assured. In a best case scenario Artificial General Intelligence (AGI) will be system capable of tapping the sum of human knowledge to answer questions which are currently beyond us and generate ideas which we are incapable of. AGI relies on a breakthrough yet to be made so in the near term we can expect that slivers of task specific Artificial Intelligence will be embedded into software, services and products in the same fashion that databases are now embedded in the such things.
