Not enough split, not really hair ;) The rewinder became obsolete, replaced by random access. Your need to seek remained. Your need to watch videos remained, relevant technologies got replaced etc. One's need for "informational pull" remains - there is no dead end.
It clearly doesn't - since so few people are using RSS.
I get that people think it's a great idea, but in practice it seems not to be.
I'm not convinced suppliers genuinely attempted to provide useful RSS feeds. Even during the hay day of RSS, many feeds were simply stubs meant to get me to their website—even for websites to which I was already paying for the content.
Regardless, demand for a particular solution is much different than demand to meet a particular need. To suggest RSS is 'obsolete' suggests its been obviated by a technology which meets the same need. I don't see that as being the case. It is far more likely to me that RSS doesn't meet the needs of the supply side.
Solutions can also be dropped for lack of profitability or other supply side concerns even where demand for that particular solution is high.
You can see this in action today. Ask yourself why Spotify doesn't support RSS for its podcasts despite it being extremely popular for fetching podcasts.
If you're reading or watching video, you're either using RSS, or using Facebook or using twitter or tiktok or YouTube or whatever. If your screen time is already dedicated to doomscrolling your Facebook feed, it's not that there was a limited market for RSS, its that there's a limited market for content in general, and people moved to where the dopamine pathways get stimulated the most.
Product optimality and market offer, "efficient" and "available", "need" and "want", do not overlap. People do not "need" palm assistants that work as mirrors (glossy displays): they buy them. One can eat mud for ignorance or for lack of alternatives.
Average Joe, Median Jack, Typical Maude and Random Randall are frequently laymen (layconsumers).
For example, all of Feedly's subscribers will only count for one pull.
