Neural networks are about as much a model of a brain as a stick man is a model of human anatomy.
I don’t think anybody knows how we actually, really learn. I’m not a neuro scientist (I’m a computer scientist specialised in AI) but I don’t think the mechanism of learning is that well understood.
AI hype-people will say that it’s “like a neural network” but I really doubt that. There is no loss-function in reality and certainly no way for the brain to perform gradient descent.
So Palantir sells a data management tool and deployment support. That shouldn’t really surprise anyone who knows the first thing about data science.
The interesting thing about Palantir isn’t what they sell but how they sell it and who buys it. They clearly market their unremarkable software as an autocrat’s wet dream.
And police and military departments across Europe and the US buy their shit, which says more about those police and military departments than about the software.
