Thats why i personaly believe that we should strive to build an A.I. to replace leadership, be it political and/or economical.

The problem with that is that the most powerful AI, the one with the most capabilities, is built by, or stewarded by the people in power. The problem is that every human is selfish, at least to some degree. Any AI coming from people will be selfish as well. Chatbot Tay might be a meme now, but I think it shows quite apptly that any alorithm that learns from humans will inevitably display human traits and greed is one of those traits.
