In 1983, at the dawn of the personal computer age, Apple Inc. in promotional film entitled "Lisa Soul Of A New Machine" touted their new computer, a 16-bit dual disk drive "personal office system", as something that would do away with "the cluttered desk, index cards, file folders, the in-out basket, [and] the calculator." (00:01)

Some of these things moved to the realm of the computer including the messy desk(top) now giving people two messy desks, a real one and a virtual one. The database-like structure of the card index also moved over, but the subjective index and its search power were substituted for a lower level concordance search.

30 years on, for most people, the value of the database idea behind the humble "index card" has long since disappeared and so it seems here as if it's "just" another piece of cluttery paper.

Appreciate the rosy framing of the juxtaposition of "past" and "future" jumping over the idea of the here and now which includes the thing they're selling, the Lisa computer. They're selling the idealized and unclear future even though it's really just today.

Dit doet me denken aan dat PKM kan functioneren als een persoonlijke geschiedenis van jezelf.

1478-1518, Notebook of Leonardo da Vinci (''The Codex Arundel''). A collection of papers written in Italian by Leonardo da Vinci (b. 1452, d. 1519), in his characteristic left-handed mirror-writing (reading from right to left), including diagrams, drawings and brief texts, covering a broad range of topics in science and art, as well as personal notes. The core of the notebook is a collection of materials that Leonardo describes as ''a collection without order, drawn from many papers, which I have copied here, hoping to arrange them later each in its place according to the subjects of which they treat'' (f. 1r), a collection he began in the house of Piero di Braccio Martelli in Florence, in 1508. To this notebook has subsequently been added a number of other loose papers containing writing and diagrams produced by Leonardo throughout his career. Decoration: Numerous diagrams.

The PKM space has gotten crazy, but mostly through bad practice, lack of history, and hype. There are a few valid points I see mirrored here, but on the whole this piece is broadly off base due to a lack of proper experience, practice and study. I definitely would recommend he take a paid course to fix the issue, but delve more deeply into recommended historical practices.

There is a heavy availability heuristic at play here. Most people in the recent/modern PKM space are enamored with the idea of zettelkasten and no one (or very few) have delved in more deeply to the history to uncover more than Luhmann. There definitely are many, many more. If we expand the circle to include looser forms like the commonplace book then we find that nearly every major thinker since the Renaissance kept some sort of note taking system and it's highly likely that their work was heavily influenced by their notes, notebooks, and commonplace books.

Hell, Newton invented the calculus in his waste book, a form of pre-commonplace book from which he apparently never got his temporary notes out into a more personal permanent form.

A short trip to even the scant references on the Wikipedia pages for commonplace book and zettelkasten will reveal a fraction of the extant examples.

Information overload goes back much further in history than the digital revolution. I might argue that information managers have tamed large portions of the beast already and we've forgotten many of the methods and as a result we're now either reinventing or rediscovering them as we transfer them to the digital space.

This is what I have been arguing all along as I've been doing my research as well.
