What may be the most revolutionary finding as more ancient Islamic manuscripts are preserved by digitization and shared with scholars around the world is the known fact (known to specialized scholars, that is) that there isn't a certain ancient text for the Quran. Just like the case with the Bible, manuscript copyists made their best efforts to copy accurately the manuscripts before them as they made new manuscripts, but mistakes happened once in a while. And, just as in the case of the Bible, tracing the copied texts back to the earliest available manuscripts, and reconstruction of what the earliest probable form of the text was, doesn't provide certainty about the original "words of God" found in the texts. (That's equally true of the Hebrew scriptures also important to Jews and of the Greek scriptures known as the New Testament.) The gradual spread of knowledge of textual criticism (that's the name of this study as a field of scholarship) in the Christian world is helping to reduce "fundamentalist" tendencies among Christians. In the Islamic world, there is a much smaller percentage of Muslims who are aware that their holy book too has many varied copies, and there is no certainty about the original text of the Quran. As this awareness increases, that could be helpful in reducing conflict over supposed divine commands that were man-made in the first place.
