"It doesn’t matter if you don’t know algorithms… But it doesn’t hurt to learn about it (because it might help you in the future). This is important. Usually you don’t use algorithm in programming a system but if it’s something that will scale fast, your understanding of algorithm might be useful."

Sigh. I'm really tired of this misunderstanding.

Literally everything you type in to an editor is an algorithm. "Learning algorithms" isn't about memorizing known facts, it's about learning how to think about programming.
