There won´t any big change for the artists. They´ll have their editors and authoring tools.
But the generated content won´t be saved as big file.
Not the final result is saved, but the way to achieve this result.

The border between artists and programmers will shrink.
Take a look at the script possibilities in most of the big modelling programs.
Then take a look at the approach of grafical programming through a network of modules.

And maybe, one day, they´ll understand each other.
