Interpolation
Since oral traditions were widely used to pass down the ancient scriptures, it is quite possible that interpolations may have been introduced along the way. The rishis, while of above ordinary intelligence, certainly could not avoid this possibility since most material available in those days (including palm leaves) were highly perishable.
Now of course, things are quite different, and books can last a few centuries. So committing the Vedic literature to written form for posterity is great, but with increasing digitization, the danger of fragmentation and interpolation is increasing. There is some suspicion that the tensions between Rishi Vaishampayana and King Janamejaya could have led to the interpolation of the Parasurama story.
To avoid Brahmanas becoming the equivalent of the Mullahs and dooming themselves to irrelevance, it is definitely important to preserve the original Sanskrit stanzas, which provide adequate context in which any interpretations or commentaries would be made. This should allow later generations of Hindus to still relate to, and leverage the wisdom of the highly intelligent rishis on the personal and spiritual nature of life, while discarding any irrelevant or anachronistic ritualistic practices.
Given the highly politicized nature of the Indian establishment today, I am not sure what can be done to preserve our heritage in dispassionate hands, without all kinds of lowlifes like the crass politicians getting involved. Most of us in secular professions have very little time to devote to continuing the oral traditions, even though some of us may know how to read/write/speak Sanskrit. I am not thinking 50-100 years into the future, but more like 2000-3000 years into the future. As long as we are humans, the same personal and spiritual issues may confront future generations also, regardless of technological advances. It is quite possible that due to climatic or societal changes, Brahmanas as a group may no longer be identifiable by that time, and their forefathers' history should not be lost like some kind of Atlantis. Brahmanas and Hindus need to think on a grander scale about what should be done in this regard.
My opinion in this matter is slightly different than that of Suresh.
Hinduism in general and Brahminism in particular encourage plurality of thought as long as the lines of thinking are intellectually sound and amenable to debate, and that debate itself remains parliamentary.
Since knowledge is one of the corner pillars of intellect, I believe it helps if one has a first hand knowledge of what is written in the scriptures. As most of our scriptures were written in Sanskrit, some knowledge of Sanskrit does help in having a direct understanding of them.
For example, we have diverse philosophies to choose from, such as Sankhya, Yoga, Mimamsa, Nyaya, Vaiseshika and Vedanta (which is nearly Buddhist according to some), and even the Sunya Vaada of Charvaka. One can even have one's own line of philosophy if he /she is intellectually capable of propounding one.
If we instead blindly go by the interpretations given by others to these texts, sooner or later we might become like those Taliban in Madrassas whose Mulla taught them that it rains when Allah uses the loo!
