Genre - the juicy red apple of the day?

Why does some word or other suddenly come to the forefront of spoken word and is thereafter heard on every tongue and in every text until we tend to lose all possible significant meaning and it becomes another of the over-used and over-abused victims of the lazy English speakers repertoire of what is fashionable and in at the moment.
Genre seems to be top of the list at present and one cannot turn on television or radio without someone mentioning it at any given and available opportunity. It is almost as if once the word is tasted as it leaves the mouth the speaker has to keep going back to the juicy apple of it all for just one more taste of fashionable speech. The trouble here is that it might be a delightful word to utter over and over but for the poor listeners the sound, in the end, seems to leave a rather sour and unwanted taste in their mouths.
No wonder that we seem not to be producing Shakespeare, Milton and Burns type literature any more, it is as if we have taken the traditional claymore and shattered the hopes of the English language by following in the footsteps of each others mutterables in the fear of ever sounding even the slightest bit original in our own speech.
Why on Earth did Edison give us the light bulb if he did not intend for each one of us in some way to see some of the light ourselves.
Humans are becoming more followers than leaders by trying to impress others we are oppressing ourselves.
