Okay, an interactive evolutionary computation environment would be a situation where bots post content and human beings are in the position to curate it. So for example a bot could easily post the news, or be in the role of journalist, by using satellite images, sensors, cameras, and some deep learning mechanisms, to produce stories based on relevant facts. When AI is able to produce content, whether it be journalism or even just nice pictures, the human beings are still the selector. So the process of selection takes place and bots compete for human attention in this atmosphere.

In the long term, human beings may be in a position where bots are being creative, producing content, and we rate it. That is basically an interactive evolutionary computer. Steemit can evolve into something like that if we want and this makes me much more bullish about Steem than most people right now.
