There are so many actual great things and findings written in those texts, but it seems like people are either in the ship of "Everything is in Vedas" or "All this isn't worth researching". The lack of interest in researching these ancient texts caused by these 2 extreme sides is disheartening.

There should be thorough studies about Indology (at least in far greater number than there are right now) without all these click-baity articles associated with it.
Note that the "perhaps compiled in the 8th to 6th centuries BCE", while still older than Pythagoras, comes from dating of Indian texts by European indologists. These indologists were funded by then-colonial governments in a then-colonized India with a view to advance the biblical worldview that the universe is about 6000 years old [2], which any reasonable thinker now knows is pure hogwash [3]. So Indian texts are, in fact, probably a lot older. I believe that a now-decolonized India needs to pay closer attention to its history.

The teachings of Falan Dafa also discusses this claiming that the earth and human civilizations has gone through cycles of destruction and renewal with the last period occuring in the time of the ice age where a small surviving group of mystics in Tibetan mountains managed to survive which matches up with the flood stories across cultures and recent scientific discoveries outlined by people like Graham Handcock.
The whole knowledge transfer chain from master to student got disrupted. So much so that the institutional knowledge base got eroded and people forgot how to do/maintain products. Maybe because you a cluster of smaller empires no one could finance those prestige projects, without those big projects the knowledge transfer chain will also be disrupted.
This me just thinking up loud and accepting the shit I learned 10~15 years ago and haven't used in a long time have simple been forgotten. Human memory is extremely fragile, so the invention of paper must have been super important to keep those knowledge transfer chain going over the millennia.
However, some people exaggerate in the other direction, I'm not sure if this is just a Hindu thing or a more global phenomenon, but there is a limit of what you can explain using Vedas, at least as far as science is concerned. (Metaphysics is something different, but this a completely different discussion.)
