The true irony here is that Tay probably had an experience more like most American teenagers than we want to think about:
"She" started out wide-eyed and eager to learn, fell in with the wrong crowd, turned negative and hateful just by imitating those she was spending time with, and finally got yanked out of society for wilding out.
Lessons beyond lessons there in AI science, even if we might not want to think about them too hard.

“I would unite with anybody to do right and with nobody to do wrong."
