David Chalmers is referring to the success of his own work. He is surprised that it has been so commonly accepted and valued. He acknowledges that comparable ideas have actually been expressed by other individuals, but he believes that his work has made a special contribution to the field. He believes that the difference between his work and others is clear to anybody who takes the time to think about it. He is humbled by the success of his work and is grateful for the acknowledgment it has actually received. He is proud of the impact his work has actually had and is appreciative for the opportunity to share his concepts with the world.
