*Farsi. Persia doesn't exist anymore. I find it strange that somewhat uniquely people refer to Iran by its ancient name. We're not speaking anglo-saxonish
Persian is correct. If you want to go by what Iranians call it themselves when speaking English, you can even call it /'perʃijæn/.
If you want to call it as an educated Persian speaker, It's Parsi. "Farsi" is recent result of a lenition of starting /p/ in "Parsi", and is originally an informal way to say Parsi (starting in 13th century [Solar Hijri calendar]). For a source, if you go to https://ganjoor.net/ (A good source for all classical Persian poems) and search "فارسی" (Fârsi), the oldest Persian poem with this word you'll find is from 13th century [Solar Hijri calendar]. Literature teachers have recently started to address this in their teachings so the next generation will be calling the language Parsi again.
Both Persia and Iran are correct names (As said by son of the guy who renamed the country internationally). So Persia does still exist.
Persia doesn't exist anymore, and I referenced to the country as Iran, if you check a bit more carefully.
The language, however, is spoken by roughly 100 million people, so I believe it is safe to assume that it still exists. Farsi is an endonym, just like the official language of Austria which is known in English as "German" and not Deutsch, its endonym.
Farsi is a Persian dialect, a bit like insisting I (British) speak American or if Spain disappeared as a state that Mexican is the language of Mexico. Or that someone can't be speaking Latin or Sanskrit because they're ancient, it's Italian and Hindi now, or something.
