Is Moore’s law slowing down?

Optimization

Bayes

R Programming

Moore’s law states, that every two years, the number of transistors used in computer chips doubles. In this blog post, we’ll have some fun fitting a logistic growth function to the increase in transistor count in computers over time to see if Moore’s law comes to a halt or if that is a myth.
