Modern AI is simply no match for the complexity likely required for harboring consciousness, says Jaan Aru

He argues that our brain’s computations are of a completely different nature than any artificial intelligence because they take place across many spatial and temporal scales and are inextricably entwined with biological materials.

AI can’t solve the brain without data that fit together

The brain's first foundation models exist because some areas of neuroscience did the slow work of developing and adopting standards to help integrate data. Artificial intelligence cannot do that work for us.
