Ask an expert what's hard about their own field and you'll get a shrug, or a list that's years out of date. Not because they're hiding it. Because getting good erases it. Here's why, in four posts:
Some experts do remember the hard parts vividly, and the best teachers train themselves to replay the beginner's view on purpose. So this is a strong tendency, not a fixed law — awareness can fight the erasure, it just doesn't happen by default.
One: they defend markets with physical assets, not code. A feature gets cloned in a quarter. A continent of warehouses or undersea cable takes a decade and billions we don't have. The moat isn't in the app.
Scott Galloway's The Four reads Amazon, Apple, Facebook and Google through one method, the T Algorithm. It runs in five steps. Here they are, in order.
The T Algorithm explains the four giants we already have better than it predicts a fifth. It's a lens for reading dominance after the fact, not a formula for building it in advance.
The Four, by Scott Galloway: a trillion-dollar edge almost never lives in the product. It hides in the dullest step of the chain nobody bothered to fix. Amazon's greatest advantage wasn't shopping. It was shipping.
So we shouldn't ask people afterward if something changed their mind. Write down what they think before, then compare it to after — because by the time we ask, the mind that would know the truth has already been erased.
We can't trust anyone's account of what they used to believe — including our own. When a mind changes, the old belief isn't stored next to the new one. It's overwritten.
This has mostly been shown on soft opinions — the death penalty, tax policy. A belief tied to one sharp memory, like doubting something until an outage in March, might survive a lot better.
