So if you know anything about manufacturing of any product, Machines cannot do the same thing over and over again nominally.
So when this phone was made or my pen or my glasses or my shirt, it doesn't really matter.
So manufacturing engineers, design engineers, mechanical engineers will give mechanical or manufacturing tolerances.
So they might say, hey, this phone has to be a quarter of a centimeter thick, plus minus two hundreds of a centimeter.
This pen or part or watch or satellite system or computer chip has to be one millimeter wide, plus minus four microns.
Why? Because as long as you're within that band of authorized tolerance, your product looks identical, acts identically, performs as you want.
So you have this Six Sigma of quality control that says, as long as you're within that tolerance band, you're pretty much what I want.
Even though all these products come out identically, let's assume they pass the quality control, they come out identical.
There are those nuanced differences, right? My phone maybe here is plus 121 of a centimeter.
There are still those manufacturing differences still within the quality band, but that exist.
So the fingerprint, if you will, is there by virtue of the fact that the thing was made.
