Much has been written about the so-called “technological singularity“. This is when machines are given sufficient intelligence to play a big role in the future of civilization. According to the wikipedia article, such a future is hard to predict.
We should not forget, however, that there has already been a singularity and we are living it. I call this the “subsistence singularity”, that occurred when mankind was freed from always searching for food, as every other animal must do. The outcome of this prior singularity, in existence for tens of thousands of years, could scarcely have been predicted. We are still trying to understand its implications even though we are in its midst.
