Not remotely surprised.
I dabble in conversational AI for work, and am currently studying its capabilities for thankfully (imo at least) positive and beneficial interactions with a customer base.
I've been telling friends and family recently that for a fairly small amount of money and time investment, I am fairly certain a highly motivated individual could influence at a minimum a local election. Given that, I imagine it would be very easy for Nations or political parties to easily manipulate individuals on a much larger scale, that IMO nearly everything on the Internet should be suspect at this point, and Reddit is atop that list.
List and Array terminology also bothers me ... Why not just call it an array?
