Artificial Intelligence is changing the world. Learn how it works and how to stay safe.
1. Understanding AI
What is AI?
Artificial Intelligence is when a computer mimics human thinking to solve problems.
Instead of following strict rules (like Python code), the AI learns from Examples (Data).
Generative AI
AI that can create new content, not just analyse it.
Large Language Models (e.g., ChatGPT) predict the next word in a sentence.
Tools like Midjourney create pixels based on text descriptions.
The instruction you give the AI. Better detail = Better result.
"Draw a cat" vs "Draw a neon cyber-cat in rain"
Training Data
AI is only as smart as the data it was fed.
If an AI learns from bad (or biased) data, it will give bad answers.
AI learns by scraping the internet. It might use artists' work without permission to learn styles.
2. Risks & Safety
Hallucinations
When an AI confidently makes up a lie.
It doesn't "know" facts; it just predicts the next likely word. Sometimes it predicts wrong but sounds right.
Algorithmic Bias
When AI treats certain groups of people unfairly.
- Example 1: An AI hiring tool rejecting female CVs because it was trained on mostly male CVs.
- Example 2: Facial recognition struggling with darker skin tones due to lack of training data.
Bias is often hidden in the training data.
Deepfakes
AI-generated video or audio that looks/sounds real but is fake.
- Fake News
- Scams (Voice cloning)
- Bullying
- Unnatural blinking
- Blurry mouth/lips
- Robotic tone
