As noted in this article, machines already outperform humans at many tasks that humans solve with intelligence. Every year, there are new breakthroughs in that direction, and the list of tasks that humans can do better than machines is rapidly shrinking. We're well on our way to solving artificial intelligence.
So why does it feel like there has been no meaningful progress at all?
Because intelligence and consciousness are different things. What we're really looking for is a machine that, like a human, decides on its own which problems to solve, and solves them without needing to be specifically directed to do so. A machine that produces not only results that its creators asked for, but entirely new ones that are not in any obvious way related to its input and programming.
It appears to me that the entire field of AI research is utterly confused about this elementary distinction.
