I think this is too linear. My two cents are that AI, when it cracks one language, many languages will be cracked after that. In other words, exponential growth. With Open Source still being prevalent, I just think the libraries will be shared as it will bring in a new era for humanity. Think about all those languages we don't even have translators for (namely those countries that have only 20 people speaking a specific derivation of a derivation of a .....of a language humanity can translate). There are almost 7,000 languages in the world [1]. Language is a tough challenge but when we find a breakthrough, it's my strong opinion, that we'll bring everyone to the table of communication.
