Summary
A Pew Research Center report indicates that over a third of web pages published since ChatGPT's launch show signs of AI authorship, with nearly 10% of a 10,000-page sample exhibiting AI creation. The study also identified common linguistic patterns, such as increased use of em dashes and specific vocabulary, as indicators of AI-generated text, noting that commercial (.com) domains are more likely to feature AI content than educational (.edu) or government (.gov) sites.
