The Man Who Invented 'AGI' Says We've Reached It — And He's Not Happy About It

"I INVENTED THE TERM and I say we have achieved AGI." Mark Gubrud's tweet on March 24 was blunt, direct, and almost immediately viral. It landed two days after Jensen Huang made the same claim on the Lex Fridman Podcast — but Gubrud's endorsement carries a weight that Huang's doesn't. He literally coined the abbreviation.

The Origin Story

In 1997, Gubrud was a physics graduate student at the University of Maryland, obsessed with the dangers of breakthrough technologies as weapons of war. He wrote a paper called "Nanotechnology and International Security" for the Fifth Foresight Conference on Molecular Nanotechnology. In it, he needed a way to distinguish the AI he was warning about — systems that could rival or surpass the human brain — from the expert systems that AI meant in the 1990s.

His definition: "Advanced artificial general intelligence — AI systems that rival or surpass the human brain in complexity and speed, that can acquire, manipulate and reason with general knowledge, and that are usable in essentially any phase of industrial or military operations where a human intelligence would otherwise be needed."

Drop the military clause, and you have the definition the entire industry uses today.

The term was independently reinvented around 2002 by Shane Legg (now Google DeepMind's chief AGI scientist) in conversations with Ben Goertzel. When Gubrud later surfaced his 1997 paper, Legg's reaction was: "Somebody pops up out of the woodwork and says, 'Oh, I came up with the term in '97,' and we're like, 'Who the hell are you?' And then sure enough, we looked it up, and he had a paper."

What He Says Now

Gubrud's full tweet: "Current models perform at roughly high-human level in command of language and general knowledge but thousands of times faster than us. Some major deficiencies remain but they're falling fast."

It's a more measured claim than Huang's. Gubrud acknowledges the gaps while arguing the threshold has been crossed. His original paper was a warning about arms races, not a celebration of technological progress. At 66, living in Colorado with no academic position and caring for his mother, he describes his situation with bitter irony: "It's taking over the world, worth literally trillions of dollars. And I am a 66-year-old with a worthless PhD and no name and no money and no job."

Why It Matters

The AGI debate has become a proxy war between industry leaders with financial stakes in the answer. When Huang declares AGI, NVIDIA stock moves. When Altman hedges, Microsoft's partnership terms shift. Gubrud has no skin in the game — no stock options, no board seats, no revenue tied to the outcome. That independence makes his confirmation harder to dismiss, even as Satya Nadella insists we're "not anywhere close."
