With regard to language committees:

This way of establishing language conventions makes for interesting possibilities. I read in the paper recently that a stone tablet was found a little outside Jerusalem with the oldest known Hebrew writing etched into it (cannot find a link!). Maybe such discoveries might allow (or force?) linguitic commissions in Israel to reevaluate features of grammar or certain usages. Maybe not too - but it's extraordinary to think that a stone buried for thousands of years can have any bearing any of today's written or spoken languages.
