Still Very Much Alive
I have stopped believing in the supernatural, so that rules out film fairies. I suspect that the factories that coat the emulsions are still going and the business is very much alive - good news for users of older analog cameras. Depending upon which camera you have, you should be able to shoot film long into the future.
Note: if you are using Leica or Hasselblad cameras they will last four years longer than forever anyway...
Note also that the pro labs are still going strong and can cope with ( nearly ) anything you can load into your camera. The lab techs might shake their heads but they soldier on anyway.
