Why Moore’s Law isn’t failing

The physics aspects of Moore’s so-called “Law” are failing, as they eventually must. Clock speeds have stopped increasing, transistor density has stopped increasing. The laws of thermodynamics and the Uncertainty Principle are seeing to that. But manufacturing costs per chip are still falling, which means that our only hope of Moore’s "Law" continuing to hold over the coming decades is to cram more and more processors into each box.
