> But that doesn't mean anything is made better by mysticism and appealing to some vague idea of transcendence.
Actually it does. Let's talk about "better". Better for what, for who?
Some of the most powerful forces for positive change are stories. Stories are made-up, vague, hand-waving. metaphorical and allegorical. They occupy a different, parallel communicative realm to science, maths and equations. But they are no less true, particularly with regard to their utility if you want to communicate important ideas to lots of people.
Certainly, mysticism is not an analytical or investigative tool. But it is a powerful communicative, and - since you raise Wittgenstein - a powerful symbolic tool for word-concepts that "stand in for" formalisms.
To be honest I think that the way the younger generations relate to smartphones, the Internet and AI is very much mysticism. The words have changed, but I don't see concepts like "The Cloud" having any more substance than "Ectoplasm" and "ethereal spirits".
Again, that new generation mysticism isn't a bad thing, it's just a way of dealing with unfathomable complexity through stories that we can all share.
