We still don’t understand general intelligence.
Roitblat notes that both humans and machines process information. But, whilst both can do so systematically, humans can also think out of the box. He points to a class of problems called insight problems. This is a problem that you wrestle with hours or days or longer and then the answer comes to you seemingly out of nowhere. Your mind suddenly chooses to look at the problem in a different way, to represent it differently, and hey presto. Common sense relies on the same mechanism. We do not understand how the brain performs these tricks. So, we still don’t know how to design artificial general intelligence.
