The oral tradition was certainly strong but there was no dearth as such of writing instruments. What makes their work not easy to access is their poetic symbolism, sun is one, moon is two and so on. These symbolisms were not even one to one, thus always leaving a window a doubt about what they really meant in their verses.

Since you mention Fibonacci, you may know what we call Fibonacci series was worked out around 250 BC by Pingala as an exercise in enumerating meter of verse

The question is why has that innovation of breakthrough ideas dried up. Past glory is small consolation, or none at all. How long will we keep sharing these 1000-year old memes in 'modern' India? Maybe innovation still happens (likely) - but no one recognizes it, and it gets lost in the endless clamor and noise of meaningless rituals that define religion in India today - or there may be no ecosystem to surface it, ie bring to market.

What religion/culture was then in the time of Aryabhata (which no one really knows I suppose) - is very likely totally different than what it is today , i.e. a way to impose majority opinions with zero debate. Because Aryabhata and others created works which made it through the centuries of strife, they survived, they had an ecosystem that supported the genius - which seems to be lacking now in Modern India - which might explain why it has dried up - i.e. Indians aspirations are far less lofty, the bar is set quite low - because there is no lack of money, there is no lack of tools. Whether now, or 1000 years ago, they were recognized as authoritative, transformative works - do we have the current generation creating anything (to which the average Indian response is the last 70 years of liberal rule has to be ruled out, and undone first).

I think its far worse. Current and in power ideology has co-opted scientific progress for romanticizing about a past, often fictional. That's why we have government patronage of fraudulent medicine-men and their medicine such as coronil that was supposed to ward off coronavirus and simultaneously fight the evil conspiracies of the western civilization that denied them their due glory.

I also misunderstood an aspect of your original comment. I thought you were waxing romantically eloquent -- look they had no pencil and paper and they would just gaze poetically at the heavens and maths would happen in their brains... just imagine what would have happened had they been given paper.

Hence my comment, that lack of writing material was not holding them back.
