Indians are not going to maintain their excellence in technology and beauty, traditions, temples, languages.

They didn't even maintain their own. It was an English historian during the imperial times who rediscovered various ancient texts there and basically created "Hinduism" by assembling their old religious beliefs. Many Indians at the time had no interest in his discoveries until elites decided to use the umbrella religion to create national cohesion. Even today a lot of Indians have no interest in preserving their famous temples and UNICEF sites. Just old buildings who gives a shit.
