When I first read this, I wasn't sure why he started out with such a pessimistic attitude about how humans can be so narrow-mindedly falling into one future is good bucket or future is bad bucket. I don't really think what will make progress is "love". I think it's going to be people actually believing in things like peace, compassion, understanding, tolerance, humility, susatainablity more than what we say we do. Like Gil Scot Heron used to say, if people believed in all that stuff as much as we say we do, we would have the world we want. I mean this in an optimistic way. We now know how to reach and teach and learn and persevere. Now we just have to work for Progress. Hopefully, we'll learn to be more efficient at it as we keep working on it.
