Since Vox launched in 2014, our audience has supported our mission in so many meaningful ways. More than 80,000 people have responded to requests to help with our reporting. Countless teachers have told us about how they're using our work in their classroom. And in the three years since we launched the Vox Contributions program, tens of thousands of people have chipped in to help keep our unique work free. We're committed to keeping our work free for all who need it, because we believe that high-quality explanatory journalism is a public good.

A few weeks ago, Wharton professor Ethan Mollick told his MBA students to play around with GPT, an artificial intelligence model, and see if the technology could write an essay based on one of the topics discussed in his course. The assignment was, admittedly, mostly a gimmick meant to illustrate the power of the technology. Still, the algorithmically generated essays -- although not perfect and a tad over-reliant on the passive voice -- were at least reasonable, Mollick recalled. They also passed another critical test: a screening by Turnitin, a popular anti-plagiarism software. AI, it seems, had suddenly gotten pretty good.
