That take is just... wild.
I've been following this space intently for two decades. The past couple years have seen revolutionary, fantastical advances. Obsidian 1.0 like just came out in September of this year! A huge milestone, but with Logseq chasing them and seeming only a months behind them (and more open source to boot).
Even the slow, web-bound proprietary dinosaurs they are replacing — Notion, Roam, etc — are only a few years old, and in their time (which is now over) those represented huge advances over clunky Evernote, OneNote, and their ilk.
All building on the shoulders of ancient, more limited tools like nvAlt, VoodooPad, Tiddlywiki, etc etc etc.
We're right on the cusp of having a bunch of choices that can help manage all your notes, including your own and your collections of other people's, with images and video and audio and PDF etc, storing it all in non-proprietary open formats, on your own infrastructure (if you want, or cloud if you prefer), with familiar and easy GUI clients for all your devices, that stay synchronized whether you prefer to pay to make that easy or prefer to leverage the open standards and do it all yourself... and we're just getting started with the potential integrations and do-it-yourself add-ons that are enabled by the basis in common/open standards.
I think has been and continues to be one of the most interesting spaces in all of computing. (Sure GPT-3 and friends are interesting, but emerging solutions in this space are also useful, and to a huge number of people to boot.)
