It sounds to me like the issue is more that we're just not used to it than anything else. It's going to be jarring. But if 48 FPS becomes the norm, we'll get used to it.
This sounds like a different situation to me. That video-style, high frame rate look has already been around for years and years, and it still looks as cheap and uncinematic as ever.
Unless everyone suddenly decides that we want all our movies to look like live stage productions or something. But I don't really see that happening.
