I have said it for years, and will continue to say it - people who want to create, will create, whether there is a reward or not. They are compelled by that desire to create.
Writing well is about expressing yourself. Sometimes that expression helps people figure things out for themselves. Sometimes, it moves others.
There's value in all things, depending on the perspective. Value on hive depends on who sees it in that seven day window, and what they choose to do with that limited timeframe.
Can it add value again in the future? Absolutely, but the Internet as a timeline as opposed to an archive is a very real thing I'm noticing these days.
New content is instantly absorbed, and old content festers. We need to value it all equally. Not everything is relevant "for the moment". Some things will be relevant always.
