Beginner friendly: Challenging

Starting a side hustle with an AI Content Personalization Engine can be challenging for the average beginner due to the technical knowledge and expertise required in AI technologies. Most people without a background in machine learning or data science may find it difficult to navigate and utilize the engine effectively. While there are online resources like tutorials and courses available, the learning curve can be steep. Additionally, setting up and configuring the engine properly can be time-consuming and complex. Therefore, the ease of starting and making a profit with this hustle is quite low. I'd rate it a 1 because the specialized skills and knowledge needed make it a challenging endeavor for someone without prior experience.
