Of course, if something was actually intelligent just as we are, but didn't need food etc, then the 'means of production' would now be wholly and completely owned by capital, and there would be no place for workers of any sort. But with LLMs we are as close to that as climbing Everest takes us to the Moon. No small feat, but not particularly relevant. After all, all they do is return statistically likely text responses from text inputs, based on a very large corpus of text previously written by humans. Any claim above that is technical hubris and/or funding strategy.
