1/8 Canary in a coalmine: A customer was not getting the numbers they expected. This was because the system took one gigabyte to be 1024**3 bytes, not 1000**3 bytes. They went on to check the numbers, not using a calculator app, but asking a Microsoft AI to convert them, not actually telling it about the base-2 thing, they just seemed to know that Microsoft likes to operate in base-2.
