That’s an interesting view, because one way I always looked at it was it became a gating function (in a negative way). Just like the rich raise the barrier to entry, I always thought that there were people who were dismissive of others because you couldn’t speak their language perfectly.

I think that's more or less the same idea as language carrying an authority. You can only use language for gating an ivory tower if the plebs believe your expensive terminology describes real and relevant facts. I think an insider language that doesn't carry this authority gets called other names, slang maybe? Also used for gating, just not as a barrier towards rising towards a higher status position in academia or rich circles.

English and the internet have this potential of bringing people together, it's quite powerful. You suddenly find out how your situation relates to people on other continents. I remember that before there was a much stronger feeling of 'other' towards people from other countries and cultures, and often the only information you could get about these others would be through the eyes of someone else. To be honest, even if the powers that be fuck up the internet beyond recognition now, that's a kind of devil difficult to stuff back into the box.
