There is a reason Eurasia ran the table for most of human history, and it has nothing to do with the people who lived there.
Jared Diamond’s argument in Guns, Germs, and Steel is that the continent runs east to west. Crops, animals, and tools spread along a single band of climate. Same latitude, same growing season, no adaptation needed. Something invented in one place worked a thousand miles away on day one. The Americas run north to south. Cross a few hundred miles and the climate flips, so every good idea had to be reinvented before it could travel. One continent compounded its knowledge. The other kept starting over.
Watch how an idea actually moves inside a company
Companies have the exact same shape, and almost nobody sees it.
A sharp sales play spreads across the whole sales team in a day. Everyone is at the same latitude. Same tools, same language, same problem. It travels for free.
Now watch that same idea try to cross into support, or ops, or finance. It stops. Different context, different vocabulary, different stack. So instead of inheriting the solved version, the next team rebuilds it from scratch. Sometimes badly. Sometimes never. And nobody feels the loss, because the rebuild looks like normal work.
This is not a documentation problem
We tell ourselves people are too busy or too lazy to write things down. So we buy another wiki and nag everyone to keep it current, and we act surprised when the same problem gets solved three separate times.
But most of the knowledge that actually matters already got written down somewhere. It just never crossed a latitude. It sat in one team’s channel, in one person’s head, in one thread nobody outside that room ever reads. Then that person changed roles and it left with them. This is what most companies still run on: Process Street calls it tribal knowledge, and it is the single most expensive thing a growing operation quietly depends on.
That is an axis problem, not an effort problem.
You fix an axis, not a folder
You do not fix an axis problem by writing more documents. You fix it by building a path for knowledge to travel across function lines, so a problem solved once becomes a repeatable process the next team can actually run, instead of a blank page they have to fill in again.
The unit that travels cannot be a memory or a good intention. It has to be the actual way the work gets done, captured so it survives the person who figured it out. When the process holds the knowledge, changing who sits in the seat does not reset the whole function to zero.
The test is simple. When your best person leaves, does the way they worked leave with them? If it does, you do not have a documentation gap. You have a continent running the wrong direction.
