You cannot ask two people to write a book review on a book, and then expect the paragraphs and sentences of the reviews to be 'mix-n-match' interchangeable...

But that they, or someone else in 200 years time, will be able to read each others reviews, or the subject book isn't such a Great Expectation.

We, or rather "certain we's" can still (or perhaps again, given the Rosetta Stone) read the hyroglyphs on 4500 year old foundations stones. Even though the "brick" it's written on isn't suitable for use in most modern buildings.
