The account seems legitimate though, long post and comment history with a clear set of specific interests and personal views. Some of which appear to be related to working in video/graphics. If this is astroturfing, it's beyond expert level.
"In local news there is a booth producer (someone who builds the show in a software like ENPS before the show and who talks in the ears of the talents and queues them during the show) then there is a technical director (the person who uses those huge boards with all the buttons to bring up supers and chyrons and switch between cameras and video channels when packages or soundbites play). Then there’s the audio operator who opens and closes faders in synchronicity with the director so they make sure anchors can talk to each other during sound bites or packages without having their mic on air, play music when we fade to commercials, play franchise music, play stinger sounds, they also do mic checks and work to establish connection with reporters backpacks -which are what we call the antennas they use to signal back to the stations for live coverage. All of these positions are being automated besides the booth producer. Which the booth producer is also just a producer, -which is someone who works in the newsroom writing stories and then booth produces the show. They will be the only one in the control room now and will just be there to speak in the ear of the on air talents and tell reporters in the field when to be ready for their shot. Everything else is being automated with AI."
