In defense of the project: they’ve been working a lot over the last 10 years. They recently published what they call a “liquid neural network” where they’ve isolated the neuron structure doing the work. It outperforms CNNs for some niche tasks, and it uses a fraction of the resources.
Just to make this clear, I think this project is actually one of the few sane engineering approaches for starting to understand how our brain works. Sure, claims of simulating a cat brain or even a human brain in some manner are much more catchy, but it seems to be pretty arrogant if we struggle even with C.elegans.
