AI commentator Daniel Faggella referenced the workflow of Anthropic's Chief Engineer, arguing that building a full-blown "second brain" will become essential for future competitiveness.
He outlined three progressive predictions:
- Human teams equipped with a second brain will outcompete those without one.
- Teams that collaborate effectively within and among these digital brains will pull further ahead.
- Teams using brain-computer interfaces (BCI) tied to these systems will ultimately dominate.
The quoted post highlights that the engineer uses Obsidian to maintain a 9,000-document knowledge graph functioning as a second brain.
