Content licensing deals between developers of artificial intelligence and content owners will not scale. www.promarket.org/2025/11/19/t.... "A handful of cherries does not make a sundae"
The False Hope of Content Licensing at Internet Scale - ProMarket
Is there a world where AI developers could get the training data they need through content licensing deals? Matthew Sag argues that content licensing deals between developers of artificial intelligence and content owners are only possible for large content owners and cannot feasibly apply to the bulk of producers and owners of content on the internet.

Australia has so much solar that it's offering everyone free electricity
Australia's extensive solar power penetration makes so much energy that the government wants to offer free electricity at peak hours.

Harvey.AI is courting law schools like Westlaw/Lexis once did, but do we really need it? After a demo, my verdict: it's ChatGPT in a black turtleneck. Good for firms needing secure doc review & RAG, but law students can already do most of this with existing tools. matthewsag.com/do-law-schoo...
