So, what your saying is that there is a perhaps linear, perhaps exponential increase, and that you are projecting that increase forward indefinitely. Let me know if this is unfair. Counter argument: does anything else work this way? E.g. Moores law had an end too right? I would argue that the core tech breakthrough (Transformer-based LLM) has been improved, but no fundamental further innovation seems to have been mad…
Not indefinitely but at least to the point where they’re smarter than humans.
If instead additional intelligence does little to speed up AI development (due to the need for other inputs like caputal and time), you could get a world where AI becomes better than humans at AI development and begins a cycle of recursive self-improvement without explosive growth leading to a singularity.
