Working memory is the quiet ceiling of intelligence — and neural interfaces could lift it

The author argues working memory is the quietest limit on human intelligence: you can understand a huge system yet only keep a tiny part active, so hard work is often just repeatedly retrieving what you already know — which is why debugging a large codebase feels like reconstructing the problem every few minutes. Key points:
- Screens (tabs, notes, search, docs, IDEs) already externalized memory, letting us keep far more information within reach.
- Neural interfaces could eventually collapse that distance: not memorizing every line, but keeping relevant structure available on demand.
- Expertise is largely building internal structure to see relationships beginners rediscover piecemeal; widening how much stays accessible would change how fast anyone reaches that level.
Conclusion: the future genius may just be an ordinary brain that keeps far more of what it knows within reach.
