The other day my wife was talking about her new job and having to take notes. For the past 30 years I've been keeping notes in text, then markdown in vim, starting with personal scripts, then vimwiki. A coworker showed me Obsidian, which while not FLOSS, does use an open standard for all its files. It pretty much does what my setup does.
Then it dawned on me that my wife and other non-techies just use whatever their computer has on it by default (i.e. OneNote). She never thought to go out and look for better productivity software. The idea that there is tons of better apps out there doesn't register. She has a phone, knows about the app store and gets tons of stuff there but as for her desktop or laptop the idea of apps outside of MS Office and the video games she plays is lost on her.
