John McWhorter, in World Affairs Journal:

Linguistic death is proceeding more rapidly even than species attrition. According to one estimate, a hundred years from now the 6,000 languages in use today will likely dwindle to 600. The question, though, is whether this is a problem.

Researchers have shown it takes about ten years to develop expertise in any of a wide variety of areas, including chess playing, music composition, painting, piano playing, swimming, tennis, and research in neuropsychology and topology.

We are the last generation, a culmination of all previous things, destroyed by the vapidity that surrounds us.
