I guess what I find off about the year is that far in the future would mean culture would have to be pretty different, to say the least. In 2250 or so years we went from the Hellenistic world, folk religions/god pantheons and regional empires to globalization, secularism and nation states.

As well as going through all the empires that rose and fell in that period of time.

So any baseline history that can be given? Or at least a overview of the different era and ages that have gone by to this point? What technological developments have happened between now and the yea 4258?
