On a side note, the section "A word about ethics" was a welcome addition. I found this:
> If we can generate realistic looking faces of any type, what are the implications for our ability to trust in what we see.
resonated with another article posted on HN (https://news.ycombinator.com/item?id=18309305) talking in part about the ethical impact of engineered addiction.
I guess very soon we will be able to generate "super-attractive" (as in "superstimuli") faces for virtual personas, according to targeted demographics and purpose (advertisement, youtube videos for kids, political messages and so on).
Rather disconcerting...
