Multithreading comes with a definite cost. Some people are eager to jump to multithreading as quickly as possible because they think it increases their competitive bandwidth. In reality, you should be thoughtful and careful about making this decision. Companies like Google grant a great deal of freedom to individual units, and, as a result, the different products and services do not fit together seamlessly. Many of Google’s services are strong enough to succeed on their own, but this means that they are succeeding in spite of, rather than because of, multithreading.
