A society either evolves so that it is based on truth ("stuff that works in practice,") or else it dies. Same goes for a species. And I submit that the same is true of Wikipedia--although Wikipedia is still extremely young compared even to the United States, let alone to the Hindus.
Any free society has an "invisible hand" that sometimes engages in "creative destruction." The process is not always pretty, and does not always provide good outcomes for all concerned, and occasionally produces a bad result for almost everyone. Sometimes, societies evolve in bad ways, and abandon the truths they had once discovered and embraced.
Yes. Destruction is an important part of the process. There is a constructive destruction and a destructive destruction. Depends how the absolute truths end up being valenced afterwards.
