We just don't have the knowledge to address the design of a human-level intelligence, given that efforts to build even synthetic ant-level intelligences have only been marginally successful to date. This is harsh, yes. But there is too much wishful thinking in AI. The feeling that real AI is just around the corner keeps researchers looking for a "magic bullet" that will crack the problem. This is analogous to the belief of medieval alchemists that they were near to transmuting lead into gold, when the principles of chemistry had not yet been discovered. Two centuries of slow, painstaking work, by men such as Lavosier, was needed to put chemistry on a sound footing. Top-down AI may be the same way. I might be wrong. Someone might pull off a miracle. But from the bottom up, we don't need a miracle. Ordinary cleverness will suffice. John Nagle
