> Google knows where I live, what job I do, where is my office, at what time I go to work in the morning, and almost every page I visit on Wikipedia. It even knows where I parked the car the last time. Is it possible that with all this information it can still mistake me for a potential buyer of that company's product?
Why would you expect them to be able to? Algorithms aren't mind readers. Just because a human could look at all those individual data points and reach that conclusion doesn't mean a computer could.
So they're able to infer where I work (the address), my type of job (based on search, stackoverflow is my first result in 50% of my searches) and where I parked the car- but they can't infer my role or the company's business?
