I don't want to throw yet more GenAI crap at this, but could RAG be a possible innovation that unlocks microtransactions?
I'm imagining a backend database of creator-submitted content. The LLM runs RAG on it, pays the creators it relied on to synthesize answers a microtransaction. Then also sells the Q-and-A as a subscription service to the end user. Maybe payouts are conditional on positive user feedback. The solution can also flag queries it sees that don't have great answers yet.
Same moat as search, not reliant on advertising.
