It is simply natural that as the internet grows and English resources become more and more valuable (a value to which AI adds), other languages will become crushed.

Frankly, I think it's not good. Yes, we are increasing short-term wealth by uniformizing everything, but in the larger scope of things, we are also locking humanity into a machine where there is less and less variation, all for the purposes of advancing technology.

And, should continued technological advancement turn out poorly for society (as it is seemingly doing with climate change, made possible only with science and technology), the lack of variation will make it almost impossible for us to adapt. It's just like in evolution: a lack of sufficient genetic variation makes it harder for populations to adapt to rapid changes.
