While I don't know a lot about him as many others do, Weber's concepts seem to have some relevance to this. More specifically, he conceptualized a theoretcial iron cage that leads to extinguishing human diversity (or at least altering it significantly) because of the power of science and bureaucracy. He envisioned that religions come about as a way to cope with this excessive power of science and bureaucracy by burying one's head in the sand and pretending it's all gone away.
I know this isn't about Weber, however, it seems that people are becoming more accustomed to science and bureaucracy (something Weber predicted and was very worried about). This makes you wonder, regardless if Weber is right or not, will science effectively squash out religion? To be clear, I don't believe faith in general will be extinguished by humanity itself and so my question is about a specific form of faith, religion. I think there will be concentrations of people that stick to their religious beliefs but do you think they'll eventually be squashed out too?
The potential danger I see in this is that those who stay with their religions will be the more devoted ones.
Also, since the "baby-boom generation" is aging and dying off, I wonder if these numbers are merely an indicator of that transistory phase from the "baby-boomers" dying off and the newer generation rising. So is that all these numbers represent or is there an alternate reason and meaning, such as the domination of science and bureaucracy in Western culture?
