> each of you interact using your native language with no friction

I wouldn't be so sure about that... Translations contain a lot of telltales and signals - even perfect translations end up as translation-specific dialect separate from natural speeches - and there are significant average content quality differences between cultures. With these signals + differences combined creating a much tighter closed loop than before, it feels to me that it's introducing concept of racial supremacism/classism to a lot of previously unaware people, in which the en-US(or en-GB) culture is not at the top of the food chain.

I mostly only care about the former of ^ that, but I don't like the latter offending wrong set of people, and I think that is slowly going on over at Twitter.

I guess these points can be true but is it worth the cost to avoid them? I much prefer this to the prior status of having friction to see international perspectives at all.
