The good thing is that it's truly a structural, mathematical language now, though still hard to learn, and it can avoid the whole his / her awkwardness for people whose gender is unknown to the writer. The gaps left by the Arabic words dropped from common use was filled by French (11% of its corpus is 1:1 to French) and if you know a Romance language, you can make pretty decent guesses.
The bad thing, on the other hand, is that Turkey is full of ancient history, and so much of that history is adorned in Imperial Turkish, using Arabic alphabet that no one can read. Even if they did, they wouldn't understand, since Imperial and Modern Turkish has diverged so much they are no longer mutually intelligible, not even the slightest clue.
It makes you feel like a foreigner in one's own country, in a way. Always found it funny that I can understand Middle English from 1300s, and I can read inscribed colonnades in Rome from 500 BC – but I can neither read nor understand Turkish from 1922.
