AGI: The Definition That Keeps Changing
Ask ten AI researchers to define AGI and you'll get ten different answers. So with that proviso, here's our stab at a plain English definition:
AGI refers to AI that can understand, learn, and apply knowledge across a wide range of tasks at a human level or better—basically an AI that can do any intellectual task that a human can do. The key difference from current AI (like the chatbots you use today) is that AGI would be able to flexibly adapt to completely new situations and learn new skills without being specifically trained for them, just like humans do. Current AI systems are typically good at specific tasks they were designed for, but struggle when you ask them to do something truly novel or outside their training. A chess-playing AI is incredibly good at chess, but can't suddenly learn to cook or write poetry. A human can do all of those things. AGI would have that same kind of general-purpose intelligence—it could reason about any problem, learn from experience in one domain and apply it to another, and essentially think and adapt the way humans do.
So if AGI is simply recreating human-level thinking, why you might ask would it be so revolutionary?
Because humans are actually rather inefficient. We stop to sleep, eat, get sick, scroll TikTok, and take vacations. We forget things. We have bad days. We can only learn so much in a lifetime. And crucially, you can't copy-paste a human genius.
But AGI could theoretically replicate human-level genius across millions of algorithms—algorithms that never rest, never forget, and can be duplicated instantly. They could work 24/7/365 at a fraction of the cost of a human employee. Imagine 10 million Einsteins working in parallel in a single data center, sharing insights in real-time, each one capable of mastering physics, then pivoting to molecular biology, then teaching themselves Mandarin over matcha.
That's the vision of AGI: not just matching human intelligence, but deploying it at a scale and speed that's simply impossible with biological brains. One breakthrough multiplied by a million. One creative solution generated, tested, and refined in the time it takes you to read this sentence.
That's why even "just" achieving human-level intelligence would be transformative—it's not the level that matters, it's the scale.
And if you don't think that's a big deal, remember this:
JUST ONE EINSTEIN CREATED OUR ENTIRE MODERN WORLD.
