Agree and disagree. For one, English and other languages are evolving faster now than before, due to the speed of communication, so spoken language in 500 years (even barring something weird like brain implants) is probably going to be even more different than modern English compared to Shakespeare.
However, there are examples of languages and documents that have been preserved, e.g. a Latin bible. Because of its status as a holy document and the vast power of the Catholic church, its tradition of teaching Latin, not just to read the bible, but conduct business and masses, the Latin in which the bible was written was very well preserved.
