Beginner friendly: Challenging

Becoming a Quantitative AI Researcher can be very difficult for the average beginner without prior experience or education in the field. This role typically requires a strong background in mathematics, statistics, computer science, and machine learning. To start earning a profit, one would need to invest significant time and effort into acquiring the necessary skills and knowledge. Online resources like specialized courses, tutorials, and academic programs can help in the learning process, but it would still be a challenging journey for someone starting from scratch. I'd rate it a 1 because the barrier to entry is high due to the specialized skills and expertise required.
