Two concepts from my initial investigation of Obsidian that resonated are “A second brain, for you, forever” and “Notes for you grandchildren”. I am a very linear thinker, but often feel the limitations of just linear thinking. Years ago, I started studying Chinese, having read from Alan Watts that the language is less linear than European languages. I did not get too far in my Chinese study, but have not lost my interest in connected, non-linear thinking. The idea of building a neural netork-like system is appealing, especially as my first brain gets older.
Obsidian is a group of text files. No matter what happens to the various proprietary software programs, there will always be ways to access plain text files. So no matter what you write, the chances that it will be lost is greatly reduced. My children and grandchildren and beyond will be able to read what I wrote. My task now is to write what they would be interested in reading.
