They definitely try to replace part of the people this way, starting with the areas where it's the easiest, but obviously it will continue to other people as the capabilities improve. A big example is sports journalism, where lots of venues have game summaries that do not involve any human who actually saw the game, but rather software embellishing some narrative from the detailed referee scoring data. Another example is autotranslation of foreign news or rewriting press releases or summarizing company financial 'news' - most publishers will eagerly skip the labor intensive and thus expensive part where journalists go and talk to people, look into old records, etc, if they can get away with that.
