Read across the corpus, a single physical thing is disappearing: **the interaction surface** — the screen, feed, or ad break where human attention was historically captured and monetized.

- **A068** opens the arc by declaring the attention economy already *fragmented* — short-form feeds have splintered attention so badly that long-cycle marketing is inefficient ([[claim-traditional-innovation-failing]]). The surface still exists, but attention on it is thin and fleeting.
- **A070** shows the *captive* version of that surface actively failing: forcing stationary viewers through unskippable ads ([[concept-captive-audience-model]]) now drives measurable churn ([[claim-captive-model-churn]]). Its fix — hand the viewer control via [[concept-ad-content-choice]] or [[concept-ad-timing-choice]] — is a *rescue* of the surface, not its replacement.
- **A007** reframes the surface as a liability: any AI that must be *invoked* on its own destination screen ([[concept-destination-experience]]) gets ignored ([[claim-invoked-ai-ignored]]); winners dissolve into [[concept-ambient-utility]].
- **A069** completes the demolition: [[concept-zero-click-commerce]] removes the ad-bearing interface entirely, transacting from intent to fulfillment with no place for advertising to intervene ([[claim-ad-revenue-collapse]]).

The throughline: attention was never the asset; it was a *proxy* for the moment of choice. As that moment moves off-screen (into ambient defaults, then into agents), the entire attention-monetization stack — impressions, clicks, ad breaks — loses its footing. This is the structural backdrop for [[cross-power-and-intermediation-inversion]] and the reason [[claim-ai-fatigue-negativity]] matters: consumers are exiting the surface emotionally before agents remove it mechanically.
