One could argue if Catholics will require computer/online instruction to learn Latin, why not teach them Aramaic instead?
But the only people who are required to have some fluency in Latin for the Latin Mass are the priests offering it, and a Catholic seminary which doesn't teach Latin is ... a very bad seminary, because that would mean its graduates can't read Catholic theology except in translation.
I every TLM missal there is the vernacular translation either on the facing page or the same page as the Latin. A semester of Latin is completely not needed to assist at the TLM.
