AI is about allowing machines to perform tasks that originally require human intelligence, such as understanding language, recognizing images, generating content, and assisting in decision-making.
Summary
AI is not a single tool, but a type of technology that helps people process information, express and make decisions.

2 min studyUpdated: 2026-05-26 Hallucination refers to AI-generated content that appears reasonable but is actually wrong, unfounded, or confusingly sourced.
Summary
The AI illusion is not intentionally deceptive, but rather the model’s ability to generate fluent answers even when uncertain.
