In other news, you can still buy buggy whips, dial-style telephones, and vinyl records, too.
Nostalgia and straight-up Luddite-like behavior are enough to keep almost anything going at some level -- no matter how low its actual utility as compared to more recent replacement tech may be.
It does generally make more sense to view new technology as adding to existing technology, rather than replacing it. After all, the invention of books didn't replace talking, and the invention of the telephone didn't make person-to-person speech obsolete.
One of the things I liked to point out back in the 1990s, when we still had tech bookstores, was that when you walked into one, the first bookcase you'd see had all the current best sellers, and if you opened them to the first pages, you'd inevitably find a URL where you could download them, usually for free. Many people would be puzzled by this. If you can download the book and display it on your screen, why would you pay so much money for a book. But the real techies generally weren't puzzled; they understood why they (or their employer ;-) would pay money for the hard copy.
Of course, amazon has now killed off most of those bookstores. But the hard-copy books are still being produced and bought, and it's still no mystery to those of us who use them. (And we do usually also have the electronic versions in our computers; don't tell anyone ... ;-)
I also periodically run across comments that music on vinyl records is still produced and selling fairly well. This also makes sense if you give up the idea that new technology replaces the old, and ask yourself what the tradeoffs might be between the various ways of doing things.
Another fun example: I've read a few analyses of the apparent fact that the population of "working" horses has been slowly growing for some decades now. Try to figure out why this might be, before you google it. As with paper books and vinyl records, it turns out there are situations where horses are cheaper or faster or better in some other important way than the available mechanical replacements. True, it's a small "market", and they'll never regain the niche taken over by tractors, but people are figuring out that they're actually a good "solution" in a number of situations.
(I've also had fun pointing out that the web has widely adopted the concept of a "scroll" text format, which used to be the epitome of totally obsolete technology. ;-)
