## About this lesson

In this lecture Zach discusses about AI applications and stresses the critical importance of understanding business requirements before diving into any project. He recounts a cautionary tale from his time at Netflix, where a $25 million initiative collapses because the team over‑promised and under‑delivered, underscoring that **80 % of AI projects fail**. Zach urges the students to invest time in the foundational layers of development, warning that rushing leads to costly mistakes. He introduces the concept of “human in the loop,” explaining when it becomes essential—particularly in high‑risk scenarios.
