I think the transformative effect of the NDE is the elephant in the room. It is on the one hand the reason why they are important. On the other, it could be a cause for dismay among those who would like to believe that this is a purely mechanical and random universe. (Just what is random anyway? That could be a whole topic in its own right).
It has been suggested for example that the ritual of baptism which may nowadays involve the sprinkling of a few drops of water, was originally a full immersion with the aim of inducing an NDE, and this as well as other varied traditions involving various initiations aiming at some visionary or spiritually transformative experience may be the historical basis of many religions.*
I'm not promoting religion, I have none, but at the same time, we'd have to be wearing blinkers (I think that's
blinders for our US cousins) to not have noticed that most of the world has some sort of belief. The idea that if spirituality is ignored it will go away seems to have outlived its usefulness. Like life itself, spiritual and mystical experiences are resilient and keep on appearing whether we want them or not.
* For example, Rupert Sheldrake talks about some of these initiation rituals including baptism in this video, starting at about 22 minutes.
