    Data Science Roadmap FAQs

    Is 3 months enough for data science?

    No, 3 months is generally not enough time to become a proficient data scientist. Data science is a complex field that requires a solid foundation in various disciplines, including mathematics, statistics, programming, and machine learning. Mastering these skills takes time and dedicated effort. While you can learn the basics in 3 months, becoming a well-rounded data scientist typically requires at least 6 months to 1 year of focused learning and practical experience.

    Can AI replace data science?

    No, AI is not likely to replace data science. While AI and machine learning are integral parts of data science, the role of a data scientist goes beyond just building and deploying AI models. Data scientists are responsible for the entire data pipeline, from data collection and cleaning to feature engineering, model development, and communicating insights to stakeholders. They also need to have a deep understanding of the business domain and the ability to solve complex, ambiguous problems. AI can assist and augment the work of data scientists, but it cannot fully replace the human expertise and decision-making required in data science.
