Intelligence vs Understanding

When a language model writes a convincing essay about climate change, does it understand climate change? Or is it doing something more like an extraordinarily sophisticated version of autocomplete - predicting which words come next based on patterns in its training data? This question sits at the heart of modern AI debates. The systems certainly behave as if they understand: they can answer follow-up questions, draw analogies, and apply concepts in novel contexts. But they can also confidently state falsehoods, fail at simple logic puzzles, and show no sign of the kind of grounded understanding that comes from actually living in the world. The practical implication matters more than the philosophical one: whether or not these systems "truly" understand, they're unreliable in ways that a genuinely understanding entity wouldn't be. You can use them as powerful tools for drafting, brainstorming and information synthesis, but treating their outputs as coming from something that understands what it's saying is a mistake that leads to overtrust, missed errors, and poor decisions.
