To quote the thesis on probabilistic chips:

> In practice replacing digital computers with an alternative computing paradigm is a risky proposition. Alternative computing architectures, such as parallel digital computers have not tended to be commercially viable, because Moore’s Law has consistently enabled conventional von Neumann architectures to render alternatives unnecessary. Besides Moore’s Law, digital computing also benefits from mature tools and expertise for optimizing performance at all levels of the system: process technology, fundamental circuits, layout and algorithms. Many engineers are simultaneously working to improve every aspect of digital technology, while alternative technologies like analog computing do not have the same kind of industry juggernaut pushing them forward.
