Moore's Law and Pixar

Something I learned from this article is that Moore's Law states that computers will get better every five years. (True) Another thing I learned from this article is that Moore's law helped pixar in making business decisions. I also learned that they used Moore's law to predict when they would be able to make Toy Story. A thing I liked about this article is that its about pixar. Another thing I like about this article is that it proves Moore's Law works. A question I have about this article is how exactly helpful is Moore's law?
