The article mentions, but doesn't elaborate, on the purpose of the notebook as a legal document. This was much more important when notebooks could be used to show priority in patent disputes, but only if well kept. My parents were both research scientists. Where my dad worked, the company patent lawyer read and critiqued your notebooks, and maintained the discipline.

Many of those rules became unnecessary when the US patent system joined the rest of the world by adopting "first to file" priority. Rules such as: Always writing in pen, and crossing things with a single strike-through.

Notebooks are still a great way to preserve the little details of "what the hell was I thinking?" A colleague told me a good notebook prevents you from having to repeat a study because you can't figure out what you did the first time.

There are still industries that require legally defensible record management -- you'll know if you're in that boat. If not, you can DIY whatever method works for you. The success metric is if you actually use it. On paper, I write in pencil because I'm more concerned about readability than a precise narrative. On the computer, Jupyter, just because nothing else really lets me document "thinking in code."
