Skepticism is the application of the null hypothesis. Building from nothing other than observables we can establish a system of order where in testable statements can be made to assert logical arguments to establish a set a first order principles via a criteria on true or false evaluations. This is the foundation of science and mathematics. To state:

>Skepticism requires an unlimited amount of work for verifying a chain of evidence

Is an equivocation that any statement that is attempted via conjecture and criticism is impossible. However, you are using a machine built entirely on those principles to communicate the idea that logical foundations are impossible. Congrats. You have won today's irony top score.
