An AI is neither sentient nor sapient. It cannot know anything about someone or something outside of its programming. What it can do is to gather input from a platform (i.e. someone's browsing behaviour on Facebook) and match it against models and data sets. If someone looks at X, he is probably interested in X. If someone looks at a bunch of related content, he probably possesses personality trait Y. If he does Z, he will probably do more of Z. That's how these models usually operate.
It takes a human to develop these models, and refine them.
In the same vein, an AI cannot natively maximise a person's attention and create compulsion patterns. What it can do is simply what it was programmed to do. It takes a human to understand the human mind, to determine how human attention and compulsion works, and then to develop a set of instructions for the AI to execute.
'It is extremely risky' refers to competing against AI-generated generic content on the basis of quality. Since the writing market does not care about quality, this is a risky strategy. To mitigate risk, you must do something else, or offer more than just quality.
