What is the long term goal of a data scientist?

The long-term goal of a data scientist should be to become a subject matter expert in a particular field of data science (be it machine learning, or predictive modelling, etc). This would ensure that the individual has sufficient knowledge and skillsets to manage all aspects of data science projects; however if certain high caliber projects come up in a particular niche field of data science; the individual has the necessary credentials to support those high-visible projects.
This would, in turn, make the individual indispensable for the organization, and the same would have a positive impact on the earnings of the individual as well.

Happy Learning :)
