A lot of the historical symbols of pride have become meaningless (or at least significantly less appreciated)
Can you give an example? A hundred years ago a rich man wore a handmade suit and a Rolex and drove around in a Rolls Royce. In a hundred years time, the only difference is that the car will fly...
A hundred years ago a Rolex was the best timekeeper you could put on your wrist. Now it's a ridiculous bauble that can barely keep time despite constant expensive maintenance. Technology has made the rich silly.
More than a hundred years ago far more absurd things than Rolex in the face of quartz digital were detailed by Veblen in The Theory of the Leisure Class
Note that what you're describing are items that are symbols of pride due to their limited accessibility. I don't think social symbols based on indicating wealth will ever go away. Collectible books like TAOCP are a different type of symbol and usually not indicative of great wealth. These non-wealth based symbols often disappear (over very long periods of time), especially when you can access the same product in a more convenient method.
