In an article on Google Translate I mentioned that there is evidence, that the Google Translate artifical intelligence developed an "Interlingua" to translate between languages, i.e. a language not spoken by anybody that serves as a bridge between different langauges - by saving natural language information in a way never done before and impossible to be defined or understood my humans. This is a pretty good example of the new kind of knowledge that appears already and will appear more often on all areas, artifical intelligence is applied on. This is due to the approach, modern AI is using to understand and elaborate on topics: Neural networks. Another popular case was the Go game first one by an AI: It was impossible for human players to predict or even understand in retrospective the "winning move". It was made by an alien intelligence not working similar to our own. The article "Our Machines Have Knowledge We'll Never Understand" by David Weinberger is an inspiring musing on this topic.
"We are increasingly relying on machines that derive conclusions from models that they themselves have created, models that are often beyond human comprehension, models that “think” about the world differently than we do.
But this comes with a price. This infusion of alien intelligence is bringing into question the assumptions embedded in our long Western tradition. We thought knowledge was about finding the order hidden in the chaos. We thought it was about simplifying the world. It looks like we were wrong. Knowing the world may require giving up on understanding it." - David Weinberger
