I expect that at some point, it will be possible to grow meat from any given set of human DNA. At this point, I see two things:

1) Lines of celebrity meat. One might be able to look forwards to, for example, an Angelina Jolie steak.

2) Middle class (well, by then the middle classes won't exist - let's just say "rich people") dinner parties in which the hostess serves her guests herself. On a plate.

Is it cannibalism if it was never part of a whole human, but was instead grown in a vat?

This fits the [Weirdtopia](https://www.lesswrong.com/posts/cWjK3SbRcLkb3gN69/building-w...) model too much to not have merit.
