I would not be surprised if organized religion, and especially certain long-standing sects of organized religions, fall in the next few hundred years. Or at least fall out of vogue- they already are in my own generation, really, although it's likely that at least some of them will rebound toward the religions of their youths.
However, I will say that partnered with the rise in atheism in my generation is a rise in "spiritual but not religious"
I literally don't think you can keep humans from believing in magic. The best you can do is get them to concede it's fantasy or something, but you literally won't stop people from following the horoscope, doing tarot readings, buying fancy rocks, and thinking something aligns their chakras.
And people growing up, even outside of organized religions, often find these things. Just, like, on instagram. Buy this jade roller. The stone aligns your energies.
