Yes. Hollywood will eventually become uncreative
No. There are endless possibilities.
Havent they already?
Many TV shows and movies are based off of real life events. If a major event were to happen, writers could use that as a source for a new film or show.
The very idea that Hollywood running out of ideas is pretty ridiculous . Everyday new books ,genres ,ideas,plots, etc are being made up everyday. With CGI and all the latest tech used in editing and animation it is practically a world with endless possibilities and when I say endless i mean ENDLESS . Think of all the movies they have made . Every movie is always different from the other. Maybe you would say that Jurassic Parks Sequel is always the same . However i disagree to that . Though the ideas they are based upon are the same , the storyline is different. small or big . Maybe in the future we would be visited by aliens and our point of view towards making movies about aliens will change to suit both species (Maybe just maybe) And by then there would probably be movie in 4D or better..... HOLLYWOOD MOVIES WITH VIRTUAL REALITY TECHNOLOGY
In a changing world, there will always be new ideas from creators. This is one of the reasons why the arts need to still be included as important.
The ever-increasingly amazing special effects you see in movies allows sci-fi movies about literally anything to become possible now. Romance stories and westerns usually recycle the same ideas over and over, but science fiction movies like Gravity, Avatar, The Martian, Interstellar, etc are now becoming possible due to how great special effects are, and the possibilities in that genre are becoming increasingly endless as special effects get better and better
They are controlling our minds so they can redo stuff over again and trick us into thinking it is new.
