Notice the quotation marks around the word "prove" in the above sentence.

That is an English language construct that is meant to show that something
is not quite right about the thing in the quotes.  In this case, I am indicating
a looser version of "prove" than would usually be expected.

If there have been an infinite number of tests done, and all are verified as
correct, we have a pretty fair idea that the next test done will also be correct...
but the verification is important... without it we cannot know for sure. The
infinite + 1st test could be the exception that disproves the conjecture.

Absolutely!  But because of our lack of information about the plan of the
device we will never know if Warren's a genius, or just another fool.
(I notice by your use of "correct" that you already know about that quote thingy
  I mentioned above ;-)

Yep!  That is the scientific method.
