This requires something other than a free market, and for China to not exist. We're not there yet. There's plenty of competition to prevent this, for now, with AI spending being an incredibly hot issue.
Then when competition really settles to monoploy or duopoly, like it always does in bigtech, it is really difficult to prove Anthropic and OpenAI enshittify their models. Same with Opus 4.6, that suddenly was worse when 4.7 came out.
I'm not following. Free markets and China will make sure that models stay bad!? Why didn't these entities already stop the progression we've seen? What has been motivating them all this time that has preventing them from stopping?
Keep in mind this was all science fiction just a few years ago.
