The clock is ticking, all right. It's counting up.
False accusations that remain unsupported by evidence or even a rational argument get more pathetic (though no less immoral) tick by tick.
Feckless prophecies of imminent coup d'etat, imminent martial law, and imminent popular revolution, when one after another has not come true or even shown any signs that it might have come true, get more ridiculous tick by tick.
Petition signatures, in the absence of any form of sustained participation by the signers, get older and less relevant tick by tick.
The kind of bluff and bluster exhibited in the OP and the linked article, with never a blow landed, never an election influenced or a paper passing peer review, gets easier to ignore, tick by tick.
Clocks count up. In a few months, there will be a tenth anniversary, and there will be some news stories mentioning 9/11 conspiracy theorists as one of a number of examples of odd sorts of psychological fallout from the event. (They will fit the "denial" slot nicely, while other examples will be classified under "anger" and "depression" and so forth.) And with no other significance than that.
Tick, tock. In about another twenty years, the beginning of a long wave of newly published memoirs and new scholarly research will reveal additional details of the events. Images and documents that were classified or held private by their owners will be made public. New dynamic models taking advantage of progress in computer technology will be created and studied. None of these will support any existing conspiracy theory (though new conspiracy theories will sometimes be invented to try to fit with them). This process will continue for decades, as it still does for WWII history.
Tick, tock. In a century, most or all of the direct participants and eyewitnesses to the events will be deceased, as they were for the American Civil War when I was a child and are for WWI today. Films (or whatever media format has replaced them) will explore alternative 9/11 histories for amusement, including inside job narratives, but these scenarios will be taken no more seriously than the possibility that Jack and Rose really stole a big diamond on the Titanic or that Hitler was really under the magical influence of Dumbledore's boyfriend. The greatest 9/11 film of the 22nd century will use it as a historical metaphor for something more recent and relevant to its audience, like the atomic bomb that somebody will probably set off somewhere, somewhere along the line.
Tick, tock. In a millennium, if it is remembered at all that some big buildings fell down in New York back in the oil age, it just might be remembered that some people thought it was an inside job, just as it is remembered today that some people once thought spiders are descendants of the Greek maiden Arachne or that a dragon eats the sun from time to time.
The clock is ticking. Counting up, because that's what clocks do. Counting all those seconds, days, years, and centuries by which any significance the Truth Movement might have had recedes into the past. Slowly, tick by tick.
