The main Moore's law like metric they track is compute in instructions per second, per dollar. That's kept on a fairly steady exponential for a century or so and doesn't seem to be slowing.

We are probably not near simulating a brain but near enough for similar functionality. Moravec estimated it by looking at the retina which was fairly well understood and seeing how much compute was needed for similar object detection etc. in his robots.
