It'd be more a return to the past, we still had a lot of latin in science a couple hundred years ago.
One very fun thing I discovered recently is that Dante (and presumably other people in the middle ages) thought that Latin was a constructed language designed to go over linguistic differences, and that's why it had a proper grammar, unlike romance languages :)
Dante was not completely wrong, since much of the written Latin we have was a formalised and standardised version, whereas Romance languages are descendants of the Latin people actually spoke.
That is very fascinating. Do you have some source on this that you could share? IIRC Dante wrote in vernacular Italian which was uncommon at the time, presumably to make his texts more approachable by common people?
