You're calling it ass covering but I kinda see it as buck-passing too. Seems like D'addario didn't want to hold the buck so they kept passing it down until it made its way back to the worker who did it.
Seems to me like that worker's ass wasn't covered at all and now everyone's all up in his shit on his socials, and the layers of management get to wash their hands, even though it's the management and executive that are pushing AI at all costs.
Going forward, I suspect one of the main employment opportunities left for humans in the AI era is "scapegoat". Corporations don't want to take any responsibility for anything. AI can't be responsible. So there's a market opportunity for a person who is willing to take a job where their main value-add is to receive the blame when something goes sideways.
What a sad dystopia we are creating.
