An Australian radio station used AI to host a show for six months without telling listeners. This synthetic DJ prank raises big questions about AI, authenticity, and just how long you can swap out humans for neural nets before anyone catches on.

Listeners unwittingly grooved to AI-generated banter, catchy playlists, and even on-air contests—all thanks to the Australian radio station’s digital ruse. With the “AI host” passing for human for half a year, radio in Australia may never sound quite the same again.
