Well, one can certainly debate that. There are discussions among historians about "the long 19th century" (1789-1914) [1] and the "short 20th century" (1914-1991) [2]. Maybe in the far future, people will talk about our times as part of a "short" or a "long" century as well. Does it really matter in the end though? I would just take these statements with a grain of salt. It's symbolism to create a feeling of urgency, a common spirit to take action or just a way to form identity.
