Watch: America's Got Talent singer deepfakes Simon Cowell

There's apparently one surefire way to impress the most irascible member of the celebrity panel of judges on NBC's reality competition show America's Got Talent. You can always just pretend to be Simon Cowell, thanks to sophisticated artificial intelligence and deepfake technology. That's exactly what singer Daniel Emmet will do during Tuesday night's episode of America's Got Talent, footage from which was released early by the TV network. And it's easy to see why. In what is really some of the best publicity that the tech company behind this effort could ever hope to achieve, the founders come out on stage with mikes.
