The fake montage -- entirely generated using artificial intelligence -- has racked up more than 600,000 "likes" on Instagram and is part of an internet fad known as "AI nostalgia," which can be confounding to those who actually lived through the decade.

Maximal Nostalgia, the Instagram account that regularly puts out such content, basks in a hugely idealized vision of the 1980s and 1990s.

The soft-focused fantasy land comes thanks to generative AI tools like OpenAI's Sora, Google's Veo or Luma AI's Ray that enable creation of strikingly realistic videos that are, at first glance, difficult to distinguish from real footage from the past.

Channels on Instagram, TikTok and YouTube look back in time through the AI-tinted lens, depicting pre-iPhone young people as being more present in the everyday, outdoors and eager to connect with others in real life.

Among the creators bringing this vision of the 1980s to life is Tavaius Dawson, a 26-year-old entrepreneur behind the account who was born nowhere near the time in question.

"People who were born in an era of smartphones and social media kind of wish they'd lived in a time when they didn't have to worry about this stuff," Dawson told AFP.

An expert eye familiar with the era could sniff out some of the anachronisms and subtle absurdities common to AI. Bike lanes in New York City back then?

But the decade has proven to have a particularly powerful allure in the AI nostalgia trend that is appreciated by young people born long after the period.

Maximal Nostalgia and other channels like it, such as Purest Nostalgia or utopic.dreamer, depict peaceful suburbs or city streets, reminiscent of feel-good movies from that period.

Signs of the rising inequality, AIDS epidemic and crack cocaine addiction of the 1980s are absent.

Styles captured in the faux videos instead pay tribute to big hair, bright clothing and padded shoulders for which the decade is known.

"You have people look at the 1950s or 1960s through rose-colored glasses, forgetting a lot of tumultuous things that were happening at those times," North Carolina State University psychology professor Anna Behler said of collective nostalgia.

"Now, we're seeing the same thing with the '80s."

Dawson was adamant that his videos aren't meant to be seen as history but simply a way to make people happy.

Harmless intentions aside, AI video quality is so realistic that it could "blur the line" between authentic scenes from the past and fiction, Behler noted with concern.

While AI is a futuristic technology, it draws from the past for nostalgic visions that bring comfort in a lonely age.

"Nostalgia isn't a gimmick; it's emotional survival," said Simon Parmeggiani, creator of the Neptunian Glitter Ball channel that mixes a touch of fantasy with its look back at the 1980s.

Alicia West Fancher, a cosmetics industry sales director, remembers living through the 1980s and found herself deeply moved by the videos.

"I teared up," Fancher told AFP. "It's definitely not a fantasized version; that's how it was."

Dawson is now ready to trade up from AI to making live-action content set in this idealized version of the 1980s or 1990s.

"One thing we're certain of is that nostalgia doesn't fade," Dawson said.
