Learning about how good algorithms work early in Year 8 is really important for a few reasons:

1. Basic Skills: Understanding time and space complexity helps students think carefully about how algorithms function.

2. Big O Notation: Knowing about $O(n)$, $O(n^2)$, and other ways to measure helps you compare how well different algorithms perform, especially as your program gets bigger.

3. Real-Life Uses: Figuring out which algorithms to use for a problem can save a lot of time and effort in your future projects.

4. Future Learning: This knowledge prepares students for more advanced topics in computer science later on.

Overall, understanding how algorithm efficiency works helps students become better programmers!
