I am not a minecraft player. But I do like to have some input beyond my typical daily routine. Advances in technology, even though I don't use as much technology as some, interest me all the same. Ray Kurtzwiel, futurist, is working on such things. Here is a link to a series of videos on that topic. Transhumanism, it is going to have to be brave new world. ( I also read the book recently) It is later in the series part 4 or so, in it, where there are computer generated block figures that think for themselves, their goal is to rule a single green block, eventually one block character learns to attack the others to defend the green block and retain domination over it. This happened without human programming? Anyway, I often wonder as I see my kids gaming evolve where all this could lead? Technology is exponentially expanding.
