Summary
As of mid-2025, about a third of newly published websites were generated by artificial intelligence. That’s a massive increase from just three years before when the number hovered around zero.
The AI written text provides fewer diverse viewpoints and is generally presented in a cheerful manner. That's all according to an early study out last month.
Marketplace’s Stephanie Hughes spoke with one of the study’s authors, Stanford University researcher Maty Bohacek, about how AI is changing the nature of the internet.
