I am personally against uploading computer-generated artworks.
I could go on a philosophical rant about why, but in general, @DreamFromTheLayer explained it pretty well: it will be entirely possible to flood Danbooru with them. A machine can generate infinite artworks. That would be a huge blow on the servers, costs will surely rise.
Not only that, it might also break some bots, since some that use danbooru as source will base following artworks not on human input, but on machine-generated artworks.
I personally see Danbooru as something like Wayback Machine: even if artists will delete their accounts or websites, whether willing or not, this storage will keep their artworks that would be otherwise lost in time.
Machine-generated artworks can sometimes be pretty, but in the end they're just that, pretty. Since they are based on other artworks, they will never be innovative.
A separate booru for machine-generated artworks might be better imo.
