The "Rosetta Stone 2.0" is a good idea. However the chance of them finding just one Rosetta Stone would be minimal. (to my knowledge there is only One rosetta stone, and that was found by chance in a desert.). Make multiple ones scattered about and with horrible images on each one. Though if archaeologists are like any of the ones from today. They wont heed warnings of a curse, and they could likely continue digging. Either way i dont think Humanities stupidity would go away ever. So whoever they are, they are boned.
