Things have changed a lot since then.
Computer vision has grown from a pie-in-the-sky idea into a sprawling field. Computers can now outperform human beings in some vision tasks, like classifying pictures — dog or wolf? — and detecting anomalies in medical images. And the way artificial “neural networks” process visual data looks increasingly dissimilar from the way humans do.
Computers are beating us at our own game by playing by different rules...
There is a lot we don’t know about human vision, but we know it doesn’t work like that. In our recent story, “A Mathematical Model Unlocks the Secrets of Vision,” Quanta described a new mathematical model that tries to explain the central mystery of human vision: how the visual cortex in the brain creates vivid, accurate representations of the world based on the scant information it receives from the retina...
(In an interview with Quanta Magazine last year, the artificial intelligence pioneer Judea Pearl made this point more generally when he argued that correlation training won’t get AI systems very far in the long run.)
