This is not true when you don't use capital that demands rent. On the contrary, the cost per advancement is actually decreasing as we develop more knowledge.
LLMs are a cognitive technology (as contrasted to a communication technology). And it will help us tremendously manage knowledge such that you can utilize it better decreasing the cost of advancement.
Whether or not it decreases the costs of advancedment would depend on what is causing advancement to have costs. Some things might be addressable by cognitive technologies, others might not.
If capital doesn't create a return evenutally, why would it invest? (Or did you mean "rent" in the narrow economics definition? But then not sure how that applies here).
