> it's a bit of a mistake to say latin disappeared but I digress
Latin is a dead language. It's not extinct (because it's used for ceremonial reasons by the Catholic Church) but it has no native speakers. This is not a remotely controversial statement. Old Church Slavonic has a similar role in Slavic Orthodox Churches and is also a dead language for the same reason.
> Nowhere in the article says that. And most smartphones do even have support (including the Icelandic keyboard).
In my defense, I can't read the article -- I linked it because this Tom Scott video[1] uses that article as a reference for the Icelandic example he gave where he explicitly says that Icelandic is not supported by modern smartphones. My phone does have Icelandic support now so I guess the statement was only true at the time he said it?
