AI is often categorized into two types: Narrow AI (Weak AI): Designed for a specific task (e.g., facial recognition, recommendation systems). General AI (Strong AI): Possesses the ability to understand, learn, and apply knowledge across a wide range of tasks, similar to human intelligence (currently theoretical).

Detailed Explanation

In this chunk, AI is classified into two main types. Narrow AI is specialized for specific tasks, making it highly effective but limited in scope. In contrast, General AI aims to replicate human-like intelligence across various domains; however, it remains largely hypothetical as it has not yet been achieved in practice.

Examples & Analogies

Consider Narrow AI like a calculator that excels at doing math but can't tell stories or identify patterns in other data. General AI, on the other hand, would be like a human who can solve math problems, write novels, and learn new skills—all at once, although presently, we do not have machines that can do this.
