Honestly from my understanding, Tay is pretty badly misrepresented. The headlines basically went as if read twitter posts, and the overwhelming negative content on it lead the algorythm to make it say really horrible stuff.

But the actuality of it was dumber, the AI side of it to my knowledge never said anything offensive. They gave the damn thing a “Say” command. which basically the trolls learned in 2 seconds and instructed it to repeat racist things.
