Chapter 2 - Lesson text updates

Chapter 02 – Artificial Intelligence (AI) and Machine Learning (ML) in a nutshell

Provide clear, concise definition for some AI/ML terms:

• Artificial Intelligence
• Machine Learning (what is difference between AI and ML)
• Supervised Learning
• Unsupervised Learning
• Generative AI

Reduce jargon use in first paragraph of 'What is Machine Learning'

Consider reducing the knowledge jump from Chapter 1 to Chapter 2:

• The shift from general AI/ML discussion (Chap 1) to specific types of AI/ML (Chap 2) could benefit from a bridge paragraph
• Consider conceptual split of the lesson into general AI/ML descriptions and specific types of AI/ML (supervised/unsupervised, generative AI, etc...)
