“Thanks to a new breed of neural network machine-learning algorithms, compelling yet fictitious video, images, voice, and text can be synthesized whole cloth. Photos of imaginary faces can be realistically fabricated by computers — their emotions, skin, age, and gender dialed in by a knob on a machine. … Videos of politicians can be produced as you might control a puppet. … But in a way, this technological leap could actually be good news for journalists.” (Says a journalism professor.)
