Beginner friendly: Challenging

Starting a side hustle in AI-Powered Surgical Planning and Navigation would be very difficult for the average beginner due to the highly specialized nature of the field. This business requires in-depth knowledge of both artificial intelligence and surgical practices, making it challenging for someone without prior experience to start earning a profit. The setup costs for such a venture can range from $100,000 to $500,000, including expenses for software, hardware, and training. Time to profit could take several years before seeing any substantial returns. Overall, I'd rate it a 1 because the steep learning curve, high initial investment, and specialized expertise needed make it extremely difficult for most people to succeed in this field.
