The problem with pen and paper is that after decades of journalling, you are going to have hundreds of notebooks to deal with. It feels like a burden and the value of the text at that point is pretty low.
You’re right, but those notebooks don’t need backups, they can’t corrupt, and they can’t be hacked into. They work during power outages, when the internet goes down, etc.
As far as I can see, the claims are so nonsensical as to be equally (non)applicable to a notebook or a text file.
- Neither needs backups. In fact, a text file is much easier to back up if you want to.
- Neither is particularly likely to be corrupted these days, but a notebook can just as easily grow moldy as a text file can be corrupted by a disk error.
- A thief can just as well break into your house and steal your notebook as a hacker can break into your computer and steal your text file.
- A pretty large chunk of computing is done on devices with a battery these days. Depending on the time of day, a notebook may not actually work well at all during a power outage.
