Those two don’t add up. You expose yourself to manipulation and control when you don’t have adequate privacy. If privacy is less of a concern to you, then manipulation equally so too.
The next day you start seeing ads on instagram for GLP-1’s, TRT, cholesterol medication, and supplements to “improve liver function”.
It may not be that the AI tool is directly manipulating you. It could simply be that your data is used or incorporated into a new AI personalization model where the manipulation happens outside of the AI tool you originally gave your data to.
I tech people how to do that all day every day without AI, we have the tools to do what you described already, and we in fact indeed do what you said already.
