1. Introduction to AI

Artificial Intelligence (AI) refers to machines that can simulate human intelligence, learning from data, making decisions, and performing tasks autonomously. AI powers everything from voice assistants like Siri and Alexa to self-driving cars and recommendation systems.

Types of AI

1. Narrow AI – Specialized AI designed for a specific task (e.g., spam filters, chatbots).
2. General AI – AI with human-like intelligence that can perform any intellectual task.
3. Super AI – Hypothetical AI that surpasses human intelligence.

2. Why Learn AI?

AI is revolutionizing industries such as healthcare, finance, marketing, and automation. Here’s why you should consider learning AI:

✔ High Demand – AI professionals are among the most sought-after experts in tech.
✔ Exciting Career Paths – AI opens doors to roles like AI Engineer, Data Scientist, and Researcher.
✔ Innovation & Creativity – Build intelligent systems that solve real-world problems.
✔ Lucrative Salaries – AI experts earn high salaries due to the demand for their skills.
✔ Automation & Efficiency – Automate repetitive tasks and improve productivity.

3. Prerequisites for Learning AI

You don’t need to be a genius to learn AI, but having some foundational knowledge can help. Here’s what you should focus on:

1. Basic Mathematics
