Past performance is not a predictor of future performance.

While it's possible the gap between GPT5 and 4 is as big as between 4 and 3, it's unlikely. The gap between 2 and 3 was much larger as the one between 3 and 4 (and similarly between 1 and 2).

Also, it's not clear that GPT5 will do this in an *economical way* once the spigot of investor money stops.
