I think the concern about the death of audiophiles is a bit melodramatic. Perhaps at the high-end spectrum but the growth in mid-fi/future-fi products that are all-in-ones that can do many things is where the growth will be.
Despite the growth of streaming as a means to "consume" music, people are still purchasing music and predominately in the physical format.
This recent article in Headphonesty talks about the growth of CD sales, particularly among younger people. With digital downloads on the decline among music buyers. Will they be listening to their CD and vinyl collection on high-end gear? No. But they will be listening on something...even if it is entry point equipment.
So if the older audiophiles are concerned that a younger generation isn't following in their footsteps it's probably because the audiophiles aren't doing a good job of mentoring younger people. If your first response to a young person who is buying a turntable for the first time is to crap on their decision to buy an entry point Audio Technica TT hooked up to Bluetooth speakers then you're missing an opportunity to encourage them on the path to enjoying their hobby of building a music collection and the opportunity to upgrade over time to better equipment that will bring out the best of their collection.
