My point is that “AGI has human intelligence” isn’t by itself enough of the equation to know whether there will be exponential or even greater-than-human speed of increase. There’s far more that factors in, including how quickly it can process, the cost of running, the hardware and energy required, etc etc

My point here was simply that there is an economic factor that trivially could make AGI less viable over humans. Maybe my example numbers were off, but my point stands.
