To become an expert in any discipline, it is important to build a solid knowledge base which can take a significant amount of time. If you build this foundation earlier than others, then you can advance on the journey faster and develop better first-principles thinking and intuition for a variety of machine learning problems. This is particularly true in the case of AI, which requires strong fundamentals in diverse topics including statistics, mathematics, programming, data analysis, presentation, and communication skills.
However, regardless of how early or late you start your career in data science, the key is to keep practicing and honing your skills, given that the field of data science is going to continue evolving rapidly. I have worked with both Bachelors’ students as well as senior IT professionals in their 30s and 40s who are equally motivated to launch their careers in data science.
Given the lack of formal degree education in data science, every data scientist I know is self-taught to an extent. With so many open-source resources, courses, code repositories and datasets available online, any ambitious and motivated person can become a good data scientist. However, to truly become a versatile data scientist, one needs to complement their learning with training from experienced industry mentors and develop a deep understanding of business domains like e-commerce, healthcare, fintech and how data science practically works in industry.
