This crazily realistic video forgery of Obama was generated by a lip-syncing AI

Regardless of which side of the political aisle you sit on, chances are you’ve got some strong opinions on “fake news.” Whether it’s comments taken out of context, or quotes being outright fabricated, fake news is a frustrating byproduct of today’s twenty-first century news cycle.

Well, we’re sorry to tell you that things are about to get much, much worse!

At least, that’s based on a frankly crazy demonstration of artificial intelligence carried out by computer scientists at the University of Washington. Using a cutting-edge artificial neural network, they’ve developed an AI that’s able to produce new video footage of former President Barack Obama speaking, which perfectly matches recorded audio of him.

“We developed an algorithm that can generate a believable video of Obama from his voice, based on a recurrent neural network that learns how to do this by analyzing hours of Obama’s weekly address footage,” Dr. Supasorn Suwajanakorn, a researcher on the project, told Digital Trends. “Unlike prior work, we never require the subject to be scanned or a speech database that consists of videos of many people saying predetermined sentences. We learn this from just existing footage. This has the potential to scale to anyone with minimal effort.”

So with that being the case, why did the researchers choose the likes of Barack Obama to carry out the jaw-dropping tech demo? No, it’s not for partisan political reasons. “The technique we used — deep learning — requires lots of data,” Suwajanakorn continued. “And this dataset is well suited because it’s large: over 20 hours, easy to collect, contains only Obama in high-res, and public-domain, which is free for researchers to use.”

It’s worth noting that the researchers aren’t creating a CGI’d version of Obama from scratch. Instead, they’re doing a more sophisticated version of what the filmmakers behind a movie like Forrest Gump did with archival footage: taking existing video and then editing it to fit new dialog. In this case, that means moving Obama’s mouth to match what he’s saying in the audio — all while incorporating everything the AI has learned about his unique mouth movements to make it appear authentic.

We’re intrigued — albeit disconcerted — to see what happens when someone mixes the University of Washington’s research with this previous project, using a neural network to mimic the voice of (among others) President Obama.

See what were we saying about the future of fake news?

Anti-surveillance clothing is getting cheaper, but don’t expect an invisibility cloak
Affordable shirts now claim to confuse facial recognition, although their protection depends heavily on the camera and software watching you
Chart, Plot, Adult

Anti-surveillance clothing is starting to look less like an art-school experiment and more like something you could actually wear outside. Shirts designed to confuse facial recognition systems now cost about as much as ordinary streetwear, although buying one won’t make you disappear.

The Guardian reports that designers are using face-like prints, unusual cuts and infrared lights to interfere with computer vision. These techniques target specific weaknesses, so their success depends on what happens to be watching you.

This spinning drone hides in plain sight using a visual illusion
This drone doesn't turn invisible. It tricks your brain into thinking it has.
Phantom Twist

For decades, engineers have chased the dream of an invisible drone. The usual approaches have involved transparent materials, camouflage coatings, or complex optical systems that bend light around an object. Researchers at Northwestern University decided to take a completely different route. Instead of hiding the drone itself, they chose to fool the human eye.

The result is Phantom Twist, an experimental drone that spins so rapidly it almost disappears into the background. It's not technically invisible, but to anyone watching, it looks more like a faint blur than a flying machine.

This smart knitted fabric can flip switches, count your steps, and even change shape
Grandma's knitting just entered its Iron Man era

For most of us, knitting brings to mind sweaters, scarves, and perhaps an ambitious grandmother determined to make winter more fashionable. Researchers at Harvard University, however, have a far more futuristic vision. They've transformed ordinary knitted fabric into a programmable material capable of changing shape, acting as an electrical switch, sensing movement, and potentially forming the foundation of tomorrow's wearable technology.

The research, published in Advanced Functional Materials by scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), demonstrates how machine-knitted textiles can "snap" between multiple stable shapes without relying on motors or rigid mechanical parts.
