I've read these AGI works by him: x, y, z. All worth your time and consideration. I've always been impressed by Goertzel's philosophy and ambition. His ideas about future mind stemming from his work on novamente seem to me to be a plausible future for our subjective experiences. He summarized these ideas in a paper about Mindplexes. However, like I think everyone else, I have no idea when AGI will come or what form it will take. I don't know if Ben's on the right track... and I would need to dedicate years in order to feel comfortable giving an answer! But I do try and keep up to date on what is being done in the field. And I wouldn't be surprised if Ben was a part of the team that made a big breakthrough!
