Traditionalism vs new approaches to things will never go away until technological progress at least stops accelerating and levels out a little bit. So, a Star Trek utopia basically, where fundamental physics has largely been nailed down.

That said, education is a separate topic, and has generally been trending in a positive direction for most of the past 4000ish years. This has actually made the conflict harsher, over time imo, as the traditionalists are starting to feel threatened at an existential level. Naturally, they're going to meet that feeling of threat with traditional methods, and I'll just let you consider our human history of conflict resolution methods to consider what that might entail.

We just don't believe in our religious books anymore, though. We used to. And that's a problem for some people. Like, the biggest problem that can exist for them, its about souls and salvation, not this "crude matter" as Yoda would say.
