>Revisiting the idea recently, Pandora, YouTube, TikTok etc have all made a business out of building a customized feed for YOU. It's become the exact opposite of what the original article predicted. Is that the opposite? If the customized feeds are selected from the same group of sources, we could still see a decrease in total number of sources even though people are more customized. Here is a simplified example. Take the 50 US states. In the past, let's assume each state had 10 news sources. Generally people would only consume 10 news sources so the overlap of source consumption in each state was pretty similar. A person in a single state consumed the same 10 news sources as anyone else in that state. Total sources of news is 500. Then we enter a globalization time. Everyone gets 10 news sources, but they are custom picked for each person. But there is now 1 source per state they are picked form. This gives us (50!/(40!10!) ~ 10 billion, assuming I remember my math correctly) combinations for 10 news sources, plenty enough that each person gets a custom selection of news sources. But the total sources of news is only 50, 1/10th of the previous example. So while each selection is more unique, the total number of captured thoughts and opinions is now 1/10th of what previously existed.
