I see people saying this a lot but I can't see a single aspect of pen & notebook that's actually better than electronic format.
Care to elaborate?
I know you were addressing the comment to someone else. However, if you do an internet search, there are lots of posts about some of the advantages of using a pen to paper journal versus electronic. There are advantages to each method/format.
I think it's hard to make a case that there is no single aspect of pen & notebook being better. That might be the case for YOU personally, but I don't think that can be generalized. For example, and of course hypothetically, maybe you have terrible handwriting and cramp up easily when handwriting for long, so a paper journal is a no-go. But for many others, the deliberative effort of putting pen to paper helps with a slower and deeper thinking, for example. That's just one example.
Others also find the aesthetics of pen and paper journalling both appealing and generative in helping to write.
Personally, I've journaled using both paper and eletronic formats. I find doing it by pen to be the most enjoyable and I enjoy browsing through my old journals. However, I find with electronic formats for me, I may sometimes write more, but I don't find browsing through electronic journals to be that interesting at all.
With a paper journal, you just pick up a book and start flipping through.
With an electronic journal, consider that after some time (a decade? or more?) that it may be hard to know what program to use to open the entries, especially if you journal in spurts and have periods of absences.
My current journaling is spread among three platforms: Scrivener, Obsidian, and now Journal app. I recognize and considered that over time, it will be hard to recall where things are and some entries might get lost.
I believe librarians have made the argument that digital print deteriorates quicker, in many ways, than paper print. The cost of keeping digital books, for example, accessible is high compared to its physical counterpart. Technologies ages and becomes extinct which means the digital books once bought may need to be converted (more $ spent) to keep it accessible. And it's not just money; it's also time keeping up with the technological deterioration. Paper really doesn't deteriorate as fast and in many cases can exist for generations!
I recently had an experience with this. About 20 years ago I thought I would try to migrate from Word to Mellel, a word processing tool that promises better multilingual features among other things. At that time, it's multilingual features was actually way better than what Word offered. It was a pain to switch between English, Japanese and Chinese all in the same document and there were encoding errors. Mellel did it just fine. I did a major project on Mellel with hundreds of documents.
Fast forward 20 years later and for totally different reasons I needed to access this Mellel document. I had long since stopped using Mellel though I still own an older version of it. I couldn't open the Mellel document I needed. Mellel had long since been updated many, many times. I was able to grab some text off of it though by forcing Word to open the document; all formatting lost and there were lots of gibberish text. Anyhow, in working with the developer, I was able to finally (after some days) open that document and convert it to Word.
But imagine if Mellel were no longer being made. I believe when I used Mellel I was on the PowerPC platform. Since then, Macs have gone Intel and now M-chip! If Mellel were no longer made, it would be difficult to get that document back.
In an interesting way, what I have found for myself is that electronic journaling helps with getting more entries down but its longevity and accessibility (for me) is highly questionable. Paper journal is much more long lasting, more accessible, doesn't deterioriate (that fast), but I'm not always able to get down more thoughts.
