A feed is a feed. It doesn't matter how it's created. There is utility to the chronological feed as there is the the algorithmic.
Curation has been happening for a very long time. The problem is that it's not enough even to curate.
For those who experience the problem, the issue really is that they have so much information of potential relevance but still can't read more than one feed item at a time (unless it's just pictures)

This wont be solved by it being curated because that introduces another problem which is whether you trust the curation.
Not sure it can ever be solved. But the feed isn't dying. It's fundamental.
