Writing needs so many emotional and mental strength to create a sophisticated and catching plot, characters, and the story itself, to think over all connections, symbols, and tendencies. This work may be very draining and some help won’t be superfluous. What about text generating apps?
To create really new and unexpected content you have to stay for a long time under the pressure of your memory, thoughts, and ideas.
But will it be that interesting for others in the end? It is easier to add and swifter to estimate the text generated out of nothing by an app or at least to borrow some ideas and develop them in a completely new way.
