AI: Still Just Curve Fitting, Not Finding a Theory of Everything

The AI Feynman algorithm is impressive, as the New York Times notes, but it doesn’t devise any laws of physics

Judea Pearl, a winner of the Turing Award (the “Nobel Prize of computing”), has argued that, “All the impressive achievements of deep learning amount to just curve fitting.” Finding patterns in data may be useful but it is not real intelligence. A recent New York Times article, “Can a Computer Devise a Theory of Everything?” suggested that Pearl is wrong because computer algorithms have moved beyond mere curve fitting. Stephen Hawking’s 1980 prediction that, “The end might not be in sight for theoretical physics, but it might be in sight for theoretical physicists” was quoted. If computers can now devise theories that make theoretical physicists redundant, then they are surely smarter than the rest of us. The program behind the…

Can a Powerful Enough Computer Work Out a Theory of Everything?

Some physicists hope so even if it would put them out of work. But is it possible?

Recently, prominent physicists were asked whether a sufficiently powerful computer could come up with a Theory of Everything, by the sheer power of crunching numbers. As a recent New York Times article by Dennis Overbye shows, physicists were divided and uncertain: “It might be possible, physicists say, but not anytime soon. And there’s no guarantee that we humans will understand the result.” But doubt, in the view of multiverse theorist Max Tegmark, means we are guilty of “carbon chauvinism”—the idea that humans could be smarter than computers. The late Stephen Hawking thought that computers would replace humans and was alarmed by the prospect. According to Overbye, Hawking had been warning that computers would start to replace physicists in particular since…
