Just because it's flashy and technically possible doesn't mean it's a good idea. I don't like them, not even for posthumously inserting actors in films.
When they inevitably fall into the wrong hands, they will use them to make politicians or big (or even small) YouTubers they don't like say things they never actually said or put them in damning scenarios they were never actually in, and then we won't know what to believe anymore, even more-so than currently.
I really hope some of that is over-reacting and fear-mongering, but ya know, Murphy's Law.

Every single level I will ever make in SMM2 will be easier than Ultra Necrozma.
