AI-Generated Content and Deepfakes

How AI is being used to create fake text, images, audio, and video — and how to spot it.

The New Challenge of AI-Generated Content

Generative AI has dramatically lowered the cost and skill required to create convincing fake content. Tools like Midjourney and DALL-E produce photorealistic images in seconds. Voice cloning can replicate anyone's voice from a few minutes of audio. Large language models can generate plausible-sounding articles, academic papers, and social media posts at scale.

In 2023, an AI-generated image of an explosion near the Pentagon briefly caused a dip in the stock market before being debunked. AI-generated robocalls using a cloned voice of President Biden targeted voters in the 2024 New Hampshire primary. These are not theoretical risks — they are current realities.

Detection is an arms race. Current AI-generated images sometimes show artifacts: irregular hands, inconsistent text, strange backgrounds, and overly smooth skin textures. But these tells are becoming less reliable as the technology improves. The long-term solution is not visual detection alone but a combination of provenance standards (like C2PA), platform labeling requirements, and critical thinking habits.
