Artificial Intelligence (AI) is not science fiction. It is around us now (e.g., for automatic plate number recognition, credit-card fraud detection), and it is here to remain. AI is also not just one technology, but a range of technologies inspired by everything from how the brain works to how ants find food. These allow computers to appear intelligent and apply more focused processing power than the human brain can produce, though usually only to narrowly defined tasks. This is why AI technology has become so important to the modern economy. AI is here and working now.
