Which of the following is not considered a driver?

The term "driver" in the context of business and marketing often refers to influential individuals or key figures who significantly impact their respective industries, shaping trends and driving innovation. In this context, Steve Jobs, Bill Gates, and Warren Buffett are recognized as drivers due to their pivotal roles in technology and finance, having created major companies and set industry standards that affected many others.

While Albert Einstein is a renowned physicist who contributed greatly to science, his influence primarily pertains to the fields of physics and philosophy rather than directly to the business or marketing sectors. His work laid the foundation for technological advancements, but he is not associated with driving contemporary business practices in the same way as the other figures mentioned. This distinction clarifies why he does not fit the definition of a "driver" in the context of this question.
