I'd just like to interject for a moment. What you're refering to as RSI, is in fact, a diffused improvement in AI technologies, or as I've recently taken to calling it, Recursive Technological Improvement. LLM-driven "RSI" is not an improvement unto the model itself, but rather an improvement to the building blocks of AI such as software systems, chips, fabs, and electrical hardware, and other vital AI technologies that produce the next round of Recursive Technological Improvement as defined by Drexler.
Many AI users experience a recursively improving technological system every day, without realizing it. Through a peculiar turn of events, the locus of improvement which is widely noticed by them is the AI models themselves, and many observers are not aware that the improvements they are observing are basically downstream of the entire economic system, as improved by RTI.
There really is an AI model, and it is improving, but it is just one part of the capabilities improvements they experience. Intelligence is the kernel: the force in the system that allocates the system's resources and attention to the other services that can be improved. The intelligence is an essential part of economic improvement, but useless by itself; it can only function in the context of a highly efficient evolving and improving economic system. Intelligence is normally used in combination with the economic system: the whole system is basically economic improvements driven by Artificial Intelligence, or Recursive Technological Improvement. All the so-called sparks of RSI are really manifestations of Recursive Technological Improvement.
