It already is, and I regret to admit I've used it.

I wonder if English will be the first to become a low trusted language as most AI research is done on the English language. “Is it in english? Probably written by a bot.” might be a common thought in ten years. Ofc eventually the big languages will catch up in marketing spam.

If this future happens, people might "fall back" to their native languages for internet writing. I'm already thinking about this: if I wrote something which could potentially get me in legal trouble, like a reverse engineering post, I would probably write it in my native language. Kind of similar to torrent trackers in Russian or obscure phone mod forums in Portuguese.

Are the results any good? Can it really generate quality copy? How is it for research on any given topic?

Even worse, armies of GPT-3s probably wage massive flamewars against each other all over the internet in an attempt to sway public opinion.

It was always inevitable though.

Yeah. And while GPT-3 output is often nonsensical, it's nonsensical in the same way a good fraction of the general public writes on the Internet. In this way, it's close to passing the Turing test - not because its good, but because real humans on generic platforms[0] are really that bad.

[0] - By that I mean platforms that aren't strongly moderated for quality of discussions, or that don't focus on niches for which the set of people interested in them already has a higher than average discourse quality.
