The practice of using a physical notebook, IMHO, is steadily fading into quaint retro irrelevance for most people in most roles.

I have seen absolutely meticulous lab notebooks before. Each page numbered and dated, cut-outs of graphs taped into the pages, that classy light-green grid-paper. Near flawless penmanship in black ink, with the rare correction crossed out, dated and initialed. Bibliographic references following a strict format in handwriting. Footnotes, FFS.

I've tried, in grad school, 20 years ago to get into the practice. Mine sucked. Non-stop, distracting corrections, maybe a dozen or more per page. Whole swathes of the notebook consisting of deep useless rabbit holes that started with a mis-conception or brain-fart, wasting space, making it a chore to even review what I was doing. I don't think of myself as particularly talented (maybe somewhat better than a fraud). But there are lots of folks like me and much smarter that have the same experience with paper notebooks.

I think really useful notebooks are something that is learned through practice, focus, and mentorship. But there are tools that are much easier to use these days. Notebook-based stuff like jupyter. I like quarto with ipynb myself (though it's not without occasionally infuriating problems).
