More than a billion people are now using artificial intelligence (AI) models regularly, for purposes ranging from work to advice about personal relationships. This trend began with the introduction of ChatGPT in November 2022, so in only three years, AI has gone from an obscure research topic in computer science to a daily tool. What makes the new AI so much more powerful than previous approaches?
The power of the new AI comes from three sources: mechanisms, causal networks, and emergent properties. Mechanisms are combinations of interconnected parts whose interactions lead to regular changes. Causal networks are systems of causes based on multiple mechanisms. Emergent properties are ones possessed by whole systems but not by their components, because the novel properties result from interactions among the components and their functional mechanisms. Current AI systems are powerful because their mechanisms interact to produce causal networks with emergent properties that approximate human intelligence.
Mechanisms
Here are the six most important mechanisms operating in AI systems such as OpenAI’s ChatGPT, Google’s Gemini, Anthropic’s Claude, xAI’s Grok, and Meta’s LLaMA.
- Neural networks: Whereas human brains contain neurons connected by synapses that allow the neurons to interact, AI networks consist of mathematical vectors that simulate the interactions of artificial neurons with trillions of connections.
- Backpropagation learning: To get smarter, AI networks learn from experience by making predictions and propagating errors back through the networks to alter the connections between neurons to increase performance.
- Training on huge databases: The growth of the internet allows AI systems to be trained on billions of documents, including websites, journal articles, and books. By learning to predict the next word in these documents, AI neural networks acquire vast amounts of information.
- Attention: Whereas attention in humans…
