I argue it's very much in the interest of human beings. It has been since we first picked up a rock and used it has a hammer. It's the ultimate tool and has the potential to bring unseen prosperity.
I believe this will displace the workers of places like the Internet Research Agency and some Marketing specialists. While that accounts for a large percentage of propaganda jobs, that is easy enough to adapt from (nor do I really care given who is generally doing it), and marketing people who I generally don't have respect for either (I mean their founding document is literally titled "Propaganda"). The real marketing pros are good at managing hard to handle talent or bad PR disasters, which are actually meaningful skills that this won't affect.
So basically no moral or real consequential impact on society whatsoever.
