Here’s a short 3-minute comedy video by Mashable that offers a “behind the scenes” look at how Facebook autotags the photos you share with the names of your friends and family. No, it’s not a sophisticated facial recognition algorithm, the video says. Instead, it’s a brilliant, dedicated, and real live human named Paul Zuckerberg.
“How does Facebook’s facial recognition really work? Meet Paul, the guy who looks through every single picture and remembers all of our faces,” Mashable writes.
