In the ad "Chicken fries beat potato loser", the robotic voiceover says: "Burger King's new chicken fries are the new potato. We are not sorry, the potato deserved this." Indeed.
In fact, the ads were not "written by AI at all", but by retained agency David Miami, the people behind many of BK's recent fun and creative manoeuvres. Still, rather than get involved in some kind of ethical reverse Turing test, just sit back and enjoy the ridiculousness of the ads.
