Josh, I apparently failed to clearly state my central argument. Allow me to try again in simpler terms: The difficulties in proceeding in both neuroscience and AI/AGI is NOT a lack of technology or clever people to apply it, but is rather a lack of understanding of the real world and how to

Well, Ray Kurzweil famously believes that AI must wait for the mapping of the brain. But if that's the case, everybody on this list may as well go home for 20 years, or start running rats in mazes. I personally think the millions of years of evolution argument is a red herring. Technological

Strongly disagree. Computational neuroscience is moving as fast as any field of science has ever moved. Computer hardware is improving as fast as any field of technology has ever improved. I would be EXTREMELY surprised if neuron-level simulation were necessary to get human-level
