If we had the ability to reanimate 1,000 people from ancient Egypt, it seems highly plausible the resources could be found to do it. These people would be a font of information from a long forgotten past. The only question is whether they could adjust to the present.

So if preserved people from the past survived long enough, it seems like historical interest could motivate people to re-animate them. There may be other motivations but that's one.

Maybe only a small selection would be reanimated at any one time. But that might others to revived later.
