The entertainment industry won’t be obsolete. It will have significantly fewer workers.

You will still have directors and producers, though their jobs will change.

You will still have script writers coming up with new plots and stories, though much of the writing may be automated.

You will still have set and costume designers, though the sets and costumes will be digital and implementation will be mostly automated.

There won’t be many workers, but the decision makers and the creators will still be employed.
