I doubted that as well, but I don't think it is--at least it's not a simple copy paste. There's an emphasis on _is_ in the last sentence which I don't think the algorithm could have generated.

However that makes one wonder if it can also learn to generate emphases, and if so, how would it format? With voice generation it can simply change its tonality but with text generation it has to demarcate it in some way--does the human say "format the output for html", for instance?
