I agree with habryka that the current speedup is probably substantially less than 3x.
However, worth keeping in mind that if it were 3x for engineering the overall AI progress speedup would be substantially lower, due to (a) non-engineering activities having a lower speedup, (b) compute bottlenecks, (c) half of the default pace of progress coming from compute.
My null hypothesis would be that programmer productivity is increasing exponentially and has been for ~2 years, and this is already being taken into account in the curves, and without this effect you would see a slower (though imo not massively slower) exponential
Exponential growth alone doesn’t imply a significant effect here, if the current absolute speedup is low.
