I think of it as a mature hobby (ie, dedicated high end stereo) that most of the participants are likely advanced in age and likely were middle aged before what we consider modern age to be with the advent of today's connected world and streamability of media.
In another 20~30 years, this concept of no GUI display to navigate content for a primo stereo setup will be an archaic past transition period.
Personally I like having a display, but I use a tablet for that and it's wired or wireless depending on what I'm doing. I like being able to sit and thumb through the tablet interface to select the content I want to listen to. No squinting at a TV screen from 8 feet away or something like that. Kind of like holding a book and I can set it down and close my eyes and lean back and the room can be dark, etc.
More and more modern tech will bleed into this hobby as the primary purchasers start to influence the demand and market. There's already movement in that sense with the idea of Streamers, class D tech everywhere, lots of new interfaces that have small displays or interface with a display if you want, etc. And of course, more and more content will no longer be physical media as the median access to internet and lossless audio both stereo and multi-channel is not just an option but will be common and expected. There will always be people who want a retro setup, but the vast majority will be streaming either from a device or via internet.
Very best,
