ChatGPT has surpassed Wikipedia in monthly active users, marking a notable shift in digital information consumption. According to Bloomberg and data from Similarweb and GWI, ChatGPT now attracts more monthly visitors than Wikipedia, which has traditionally been a primary resource for learners worldwide. This milestone reflects the growing role of artificial intelligence as a new medium for acquiring knowledge, with some users describing ChatGPT as an "operating system" for younger generations. The change underscores the rapid adoption of AI technologies in everyday information access and learning.
