I'd argue that "value creation" is already at a decent position considering generative AI and the usecase as "interactive search engine" alone.
Regarding "value extraction": Advertising should always be an option here, just like it was for radio, television and online content in general in the past.
Preventing smaller entities (or private persons even) from just doing their own thing and making their own models seems like the biggest difficulty long term to me (from the perspective of the "rent seeking" tech giant).
