What we see is another layer of cleanup of older media, where large amounts are culled from the next generation's minds, but some will still remain. The culling first gets rid of chaff, and eventually just leaves the very best examples of old art. You can watch black and white movies on streaming services today, and the average quality is going to be extremely high, as all but the very best has been washed away. My teenage son and his friends don't just look at current media, but old one too. Kids born in 2010 that just realize there was some great music in the 70s too, and that today decide that some old videogames are still worth playing, while many have aged way too poorly. Some will get remade, maybe badly, and other parts abandoned. Monty Python's sketches are still funny to them, but the media is relatively low quality, and that style of humor has already been absorbed into the comedy corpus. Something as absurd as the parrot sketch wasn't just funny, but also felt new to many audiences. Today you find absurdity even in something like Rick and Morty, just in faster packages, relying less on repetition to try to elevate the bit. Trying to hammer at the core joke 8 times in a row is out of fashion. Now the repetition comes with longer spacing, or from different directions: See how meme images work.
