What is artificial general intelligence (AGI) and how close are we to it?

Artificial general intelligence, or AGI, is a type of AI that could understand, learn, and apply knowledge across any domain at least as well as a human can — but right now it does not exist and experts disagree sharply on when it might. Today's AI systems are narrow. They're very good at specific things like writing, coding, or image generation, but they can't transfer those skills to unfamiliar situations the way people do. A model that writes excellent marketing copy can't suddenly diagnose a medical condition or fix your car. AGI would be able to do all of those things, or at least learn to do them quickly, without being specifically trained for each one. Here's a concrete example. GPT-5 or Claude 4 can write a Python script if you ask. They can also summarize a legal document. But if you asked them to learn a brand-new board game by watching two people play it, then play it competently, they'd struggle. An AGI system would watch, figure out the rules, develop a strategy, and play — the way a smart human would. Where will AGI come from? Nobody knows for sure. Some researchers think scaling up current transformer models with more data and compute will eventually get us there. Others argue we need fundamentally new architectures. Yann LeCun, Meta's chief AI scientist, has said publicly that large language models alone won't reach AGI because they don't understand the physical world. Demis Hassabis at Google DeepMind takes a different view, predicting AGI could arrive within a decade. The honest answer is that timelines range from 'a few years' to 'decades' to 'never.' One useful tip: don't get distracted by AGI hype. The practical question for most people isn't when AGI arrives, it's how to use today's AI tools well.
