There are teams working on that as well. But, since God gave Moses a written down set of His laws, and since we are told to read and study the Scriptures over and over, and since Jesus obviously could read and write, shouldn't we also strive to give a written copy of the Word so we all can check what our preachers teach? Remember the Bereans!

https://ourworldindata.org/literacy
Of the world population older than 15 years 86% are literate.
That means 14% of the world’s population cannot read or write.
Since the world’s population is 7.8 Billion ( see here: https://www.worldometers.info/world-population/ ), that would mean about 1 BILLION people cannot read or write!
They either need to be educated so that they can read the Bible in their language, or other audio-visual means have to be made available for them.
