The difference is that they can't legally collect data _on americans_, so they need to outsource it to private companies. Non americans have no rights so they can just spy on them (through the cloud act for example).

In general emoji are very us-centric, for example the police car emoji doesn't look like a police car to many cultures.
Similarly if you find a bug in the live system, you add a test for that and the initial output will be wrong. Then you fix your code until it prints the correct value and commit that so any regression will be caught.
For example, you start with the inputs and you apply the first layer of transformations, then check what it does makes sense. Then maybe you refactor it out in its own function and add the generated test for it. Then you move on the next step and so on until you have the final result.
You can also test that the sequence is increasing like `fib(n+2) > fib(n+1) > fib(n)`.
