Artificial intelligence is a notion that has become synonymous with technological advances in computer science, primarily based on some form of machine learning. In reality, the field of artificial intelligence research has a history that goes back to the 1950s and constitutes so much more and sometimes even something completely different than what common conception usually ascribes artificial intelligence to be. This talk provides a brief history of artificial intelligence research from the field's inception in 1956 to today, going through two "waves of AI" commonly associated with the notions of knowledge-driven and data-driven AI respectively. We also consider what makes up artificial intelligence and how this influences what we do in artificial intelligence research. We end with a brief look at a possible third wave of AI, bringing the human into the centre of artificial intelligence.
