I mean apart from the technical expertise on freezing etc, the rest is mostly wishful thinking about how such a facility will survive long enough in tact (and the US wont itself go the way of the Assyrian, the Persian, the Roman, the British and other empires, in 1 or 2 centuries time), technical/medical resurrection will be possible, and future people will care to resurrect those in there.
Even if a great current mind was preserved there, if people of the future are, say 2x brighter than us (not to mention having access to advanced AI) it would make little sense want to resurrect them for that alone. And as for having access to 20th-21st century info, with our trillions of bytes of video, images, texts and sound recorded every day, they'll likely want LESS, not more information about our times.
