I ran across a perfect definition of myself today. It is in the first paragraph of a “Quora” article by Ed Robertson:
“Languages spoken by humans evolve and change through time, but they are not evolving from being simple to being complex. No language stays the same from one generation to the next. They change, mostly imperceptibly, until one day some grumpy old man or woman grumbles that young people don’t speak “properly” any more.”
I am the grumpy old man.
