When I ask ChatGPT to define almost any topic and provide some number of citations, almost every link it provides is broken. The only links I’ve found that work are specifically when I ask it to include a citation to a Wikipedia article.
In the citations it provides, ChatGPT will often include supposed quotations taken from the sources. I have yet to find an exact quote that ChatGPT presents as quoted content. I’ve run dozens of quotes through Google search and found none of them.
