Chapter 40 Exercises: Emerging Frontiers

These exercises are organized into five tiers based on Bloom's taxonomy, progressing from basic recall through creative synthesis. The exercises address emerging trends in AI-assisted development, from collaborative AI and formal verification to self-healing systems and quantum computing. Later tiers build on concepts reinforced in earlier ones.

Tier 1: Recall and Comprehension
