I keep electronic logs. Nonetheless:
the suggestion that a paper logbook(or any archived info) is more permanent, better protected/secured against being lost, damaged or misplaced and will stand the test of time better and with less effort than a digital one is IMO (also as a computer engineer... for whatever that's worth) nonsense.
Our entire modern world refutes that assertion, doesn't stop someone from preferring paper, but lets not base it on erroneous rationale.
I work in IT, have for a Very Long Time, and have some personal records and things, in electronic form, that were, at the time, intended to be permanent.
Some of them are on
nine track tape.
I had some stuff on various sizes of floppy disks which I migrated as new formats came out, for a while, but still have some that use
3.5" floppy discs.
I have some stuff on hard disks with backups to CD-Rs, and things, but that are difficult to access because they were written in the now-obsolete
Wordpad format, which cannot be opened by modern word processors.
Things in more specialized formats, like some of the music notation formats and old financial/tax software, require more arcane software, in some cases software that does not run on modern computer systems.
With time, money, and effort, I suppose I could probably read any of this stuff. But it doesn't exactly peg my fun-o-meter to screw around for an afternoon trying to read old files, the same way it does to look through an old notebook or something.
The problem is not a new one. Libraries and archives deal with it all the time. The general rule curators cite is that the media itself will usually outlive the playback equipment. In 10, 20, 50 years, will you be able to find a USB stick reader?
