When AI becomes so good that you can't detect it any longer, what will we be upvoting then?

I think this has already happened on facebook at least. Sometimes I see a post that looks really good. And then I see AI sign next to that post. This is a bit depressing.

Also a bit off topic. Yesterday I wrote this comment Do you think that trying to invite some anime/ tv series reactors to Hive could work out? Or would that cause more problems than it is worth?
