How would you build a conscious machine? Well to begin with I’d get Life Insurance and then take my brain and put it in a jar and freeze my body. Then hundreds of years later wake me up and transplant me into an IronMan. Yes, I partially got that idea from the movie IronMan and from Futurama. I’m still going to do it though. But more to the point, Christof Koch and Giulio Tononi both have good points of in their articles that they wrote on consciousness and robots.
