AI is a technical term with roots in computer science. That's not an appeal to authority - it's a factual statement.

When a layperson hears "AI" they often think of AGI - something like HAL 9000. Then they look at ChatGPT, conclude the LLM isn't (generally) intelligent, and decide it therefore isn't AI. My point is that the term has a specific meaning and it's not what most people think. I assumed you were one of those people. It doesn't imply general intelligence. A very simple system can still be artificially intelligent in the classical definition of the term. A sudoku solver, a chess engine, and a navigator would all count.

Nowadays the meaning has shifted a little and usually refers to a model that has learned from a bunch of data. By that definition none of the earlier examples qualify anymore except for LLMs.
