The old do not understand what the young do. And because the elders have learned so many things in their long lives and know so much, and yet all this knowledge cannot really explain what the young do, the elders are at a loss for a moment. And then the old people explain that what the young are doing as nonsense.

The young themselves cannot really explain what they are doing, either. The young have not yet found the right words. Because it takes a long time to find the right words. Finding the right words to describe something new, something that did not even exist in the past, takes years and decades. So the young cannot yet have words to describe the new. But the young feel that what they are doing is not nonsense.

They just don’t have the words to explain to the monkeys, who need words to understand.
