"Effective altruism is an advance in ethical behavior as well as in the practical application of our ability to reason. I have described it as an emerging movement, and that term suggests that it will continue to develop and spread. If it does, then once there is a critical mass of effective altruists, it will no longer seem odd for anyone to regard bringing about "the most good I can do" as an important life goal. If effective altruism does become mainstream, I would expect it to spread more rapidly, for then it will be apparent that it is easy to do a great deal of good and feel better about your life as a result."
