I work from home and still prefer living in the city center, despite being more expensive. Not due to the museums but due to the closeness to restaurants, pubs and clubs. How am I supposed to go back home if I am drunk and I cannot drive. The city center is for the people not for office buildings.
I really hope so, it should be taught, because for me it was a slow learning process. First I started using Obsidian, and moving all my notes from Evernote, Notion, and others manually. After that I moved to Logseq, which is like Obsidian but open-source. And the last step was using an open-source syncing tool (Syncthing) to have my notes synced locally in all devices. And now I have been 2 years self-hosting my notes in a really easy way.
There is already an opensource alternative to Obsidian, its name is #Logseq, you have mobile and desktop app
