Whats after Data Science?

The career roadway after Data Science depends largely on the interests of the individual. Post becoming an expert in the field of Data Science, if the individual yearns to seek a career in management & business strategy; then he may shift roles and use his/her experience of business problem solving to devise optimal strategies for the business.
Alternately, if the individual wishes to go deep into the world of technology; the next level is known as ‘scientific computing’ which tends to model the underlying process rather than simply the data to predict outcomes (which is the case with data science & machine learning).
