In 2004, DARPA and John McCarthy organised a Workshop on Self-Aware Computing Systems because the topic of artificial self-awareness was gaining momentum. It was a workshop by invitation at Washington D.C. Most participants came from USA, but there were two from Europe: Aaron Sloman from UK and Ricardo Sanz from Spain.
These were the thirty-three participants in the workshop:
| Aaron Sloman | Eyal Amir | Push Singh |
| Bernard Baars | James Van Overschelde | Raghu Ramakrishnan |
| Brian Williams | John McCarthy | Ricardo Sanz |
| Greg Sullivan | Ken Forbus | Richard Scherl |
| Danny Bobrow | Tom Hinrichs | Richard Gabriel |
| Markus Fromhertz | Len Schubert | Richard Thomason |
| Deborah McGuinness | Lokendra Shastri | Robert Stroud |
| Drew McDermott | Michael Cox | Sheila McIlraith |
| Don Perlis | Michael Whitbrock | Stan Franklin |
| Mike Anderson | Mike Anderson | Stuart Shapiro |
| Tim Oates | Owen Holland | Yaron Shlomi |
During three days we discussed the possibilities and approaches to machine self-awareness, within the specific pespective of artificial intelligence. Twenty years after, the discussion remains at the same point. Not much advance has been produced
Maybe the problem is too difficult for human minds.
