Here's something that looks like it could make a difference -- to scholars. We think we know a lot about early Greek culture, based on, really, a small sample of writing that has survived. (I had to read some of and maybe you did, too. Euripides, that lot.) But now, we've got a a whole lot more material to review.
Of course, I'm still waiting for the promise of the Dead Sea Scrolls to be fulfilled. You know. The part where they find the lost or suppressed Eleventh Commandment. The one that said, "Thou shalt not tithe; neither shall thou suffer thy purse to be lightened by taxes."
