I used this in conversation, and I had forgotten where I had seen it. I think this might be the original source for me:
Of all the prejudices of pundits, presentism is the strongest. It is the assumption that what is happening now is going to keep on happening, without anything happening to stop it. If the West has broken down the Berlin Wall and McDonald’s opens in St. Petersburg, then history is over and Thomas Friedman is content. If, by a margin so small that in a voice vote you would have no idea who won, Brexit happens; or if, by a trick of an antique electoral system designed to give country people more power than city people, a Donald Trump is elected, then pluralist constitutional democracy is finished. The liberal millennium was upon us as the year 2000 dawned; fifteen years later, the autocratic apocalypse is at hand. Thomas Friedman is concerned.
You would think that people who think for a living would pause and reflect that whatever is happening usually does stop happening, and something else happens in its place; a baby who is crying now will stop crying sooner or later. Exhaustion, or a change of mood, or a passing sound, or a bright light, something, always happens next. But for the parents the wait can feel the same as forever, and for many pundits, too, now is the only time worth knowing, for now is when the baby is crying and now is when they’re selling your books.
And so the death-of-liberalism tomes and eulogies are having their day, with the publishers who bet on apocalypse rubbing their hands with pleasure and the ones who gambled on more of the same weeping like, well, babies.”-Adam Gopnick, “Are Liberals on the Wrong Side of History?” The New Yorker.

I probably came across the reference in John Naughton’s online diary, which is excellent and worth using an RSS reader for.
