In Star Trek: Picard (2020), Synths (AI robots)
attacked Mars at large scale
which led to their ban by the Federation. But, it later turned out that Romulans (a natural species) were behind this to falsely defame Synths so that they can be banned.
This wasn't my first encounter with this. In the Doctor Who episode Kerblam (2018), similar plot was shown.
Interestingly, I can't remember any earlier instance of this despite seeing countless stories showing hate against AIs. I can't believe that this concept of falsely defaming AI is new.
Which Sci-Fi work first showed the plot of falsely defaming AI?
