This is a very pessimistic view of the world. Not all ads are attempts to hijack your brain. For example, if you were already thinking about buying a specific keyboard and then saw an ad for that same keyboard with a 10% discount, that ad would have actually provided positive value to you. You save money for the thing that you already want. Not all ads are like that, but the example goes to show that there is a spectrum and that its not black and white.
