Ask HN: Does taking notes help? Is it worth it to use systems like Zettelkasten?

There is quite a fuzz about taking notes and systems like Zettelkasten lately. Roam Research (https://roamresearch.com/) contributed to these things going viral.

I have a question regarding this: do these systems help in the context of programming/software development/computer science? Does note taking help you to understand, remember and learn things?

I am quite struggling if I should take on such a system myself and what the benefits and disadvantages are.
