The pervasive nature of advertising can subtly dictate the rhythm of our lives, often reducing moments of potential introspection, creativity, or connection with others into opportunities for commercial engagement. It’s a constant auction of our attention at the cost of personal enrichment and depth of experience.
It alters our relationship with ourselves and with the world, as our attention is steadily guided away from personal priorities and towards commercial ones. This is a critical and largely unexamined impact of advertising. We are, effectively, paying the ultimate price, which is life itself. No amount of "taste" in individual ads can compensate for this.
This is not true. This is the excuse used to justify the spying.
Contextual ads work perfectly well for providing information about new or niche products. It the other, much creepier, use case for ads that want the detailed information to target tailored ads at individual users.
