I think J9 is oblivious to the whole concept of things filling up space.
I've always seen technology being about convergence, the new things replacing the old things unless the old thing has a special merit to it.
I see that merit in vinyl - that nice warm tone - but not the skipping of CDs and white noise on cassettes, so MP3/AAC and Vinyl remain of use. I see a point to graphic novels, but not comic books - so I buy graphic novel roll-ups and download digital comics now. I just don't need those childhood remnants in my closet when I can get them cheaper and read them on my phone now. I find the ideas of collecting DVDs and Blu Rays to be silly unless you're a movie buff or just really like a particular movie that much. I have like two DVDs and a Blu Ray now, I stream most of my movies and TV show now.
One day, I hopefully won't have much of a closet to clean and holographic clothing will be a thing, at least for spring and summer.
