It's only obvious in retrospect. Every step along the way, there has been thousands of people saying "this is impossible" or "this is theoretically possible, but it can't be engineered" or "this is possible in principle, but it will be so costly to develop that it doesn't make sense". When AGI is developed, it will seem obvious in retrospect. Participating engineers will receive middle-brow dismissals saying that this was obviously practically possible, since after all the human brain operates according to the laws of physics.
