Look at PartiallyTyped's comment in this thread. It's a great explanation of the basic concepts behind modern machine learning. You're quite correct that modern neural networks have nothing to do with how the brain learns or with any kind of superintelligence. And people know this. But these technologies have valuable practical applications. They're good at what they were made to do.
