I believe that something resembling religion will reappear in society (American society, I mean) in the future, maybe even the near future. Political substitutes for religion have given meaning to people's lives, i.e made them feel apart of something greater, but they have not provided them with physical community, a path toward self-improvement, a guide for how to manage interpersonal relations (Apart from "don't offend people", in the case of progressivism, I guess?), or any compelling reason not to be afraid of death.

Traditional religion's staying power came not from oppressive power structures or whatever people think these days, but because of all of that. Just having an oppressive power structure and none of the other stuff has generally led to religions/philosophies dying out within a few generations, like Nazism or communism. Both of those had their time to shine, completely ruined the societies they took over, and are now viewed as jokes by most people today. Meanwhile Christianity, Islam, Buddhism, Hinduism, etc, which offer way more than ideology ever has, have been around for millennia and are on track to stay around for millennia more.
