8K TV sets will mark the return of the good old slide projector in homes. It was about time! As much as I like prints, I missed a large, high resolution & wide gamut transparency rendering of photos.
As for prints, there will certainly be a few of them in every home for the foreseable future. What worries me, though, is that entry level photo printers such as 13" and 17" models might be relegated to a niche product and will become too expensive for hobby photographers. High volume printers will likely not be affected by this trend.
This would be like finding a dedicated film scanner in the present market. Ten years ago, they were ubiquitous and there were many models to choose from, even middle range models. Now only a few high-end Imacons and drum scanners survive in pro processing facilities.
Cheers,
