Social media has proved an essential tool for catalyzing political activism and social change around the world. Yet, the very features that make it so useful to those with greater-good intentions—scalability, mobility, and low costs to entry—also make it prone to manipulation by malign actors who use it to spread disinformation and divisive rhetoric. These bad actors looking to sway public opinion include both fringe groups and well-funded, highly staffed government institutions. With the US presidential election approaching, voters and policymakers are rightly concerned with what should be done to mitigate the flurry of fake news stemming from beyond the border.
Disinformation and distrust online are set to take a turn for the worse. Rapid advances in deep-learning algorithms to synthesize video and audio content have made possible the production of “deep fakes”—highly realistic and difficult-to-detect depictions of real people doing or saying things they never said or did. As this technology spreads, the ability to produce bogus yet credible video and audio content will come within the reach of an ever-larger array of governments, nonstate actors, and individuals. As a result, the ability to advance lies using hyperrealistic, fake evidence is poised for a great leap forward.
