Simple rule-based systems

The most basic kind of symbolic AI: a system that automates a single decision using basic if-then logic. A light-sensing plug that switches on outdoor lights at sunset, or a basic programmable thermostat. Very limited, very good at the one thing it does.

Terms like this come up in real clinical scenarios across the HelloAI courses: bite-sized modules with verifiable certificates. An account takes one minute, no password needed.
