Incidentally, as its central estimate for algorithmic improvement, the takeoff speeds model uses AI and Efficiency’s ~1.7x per year, and then halves it to ~1.3x per year (because todays’ algorithmic progress might not generalize to TAI). If you’re at 2x per year, then you should maybe increase the “returns to software” from 1.25 to ~3.5, which would cut the model’s timelines by something like 3 years. (More on longer timelines, less on shorter timelines.)
Nice, gotcha.
