Spot on. :) Many subjects you touched upon, but first there is lot of misconceptions about AI..Dare to say that 95 percent of people have no clue what actually AI is. (Hint, just a huge databases, algorithmically driven and controlled within neural networks).
Training literally means, filling up databases with data.
Has nothing to do with "intelligence" as people concieve it.
Reminds me on the beginnings of Internet or social media. It took time when an actual understanding of technology took place.

And yes..any kind of intelligence, organic or artificial by definition is a threat to this civilisation. No doubt about it. :)
