You are forgetting about the end of the Moore's law. The costs for running a large scale AI won't drop dramatically. Any optimizations will require non-trivial expensive PhD Bell Labs level research. Running intelligent LLMs will be financially accessible only to a few mega corps in the US and China (and perhaps to the European government). The AI "safety" teams will control the public discourse. Traditional search engines that blacklist websites with dissenting opinions will be viewed as the benevolent free speech dinosaurs of the past.
