Right, my point is that we don't have the data to make a similar exponential argument. We can't rule out the possibility that we're currently in the early stages of exponential growth based on direct measurement. If it is exponential, once it doubles enough times, it will show up in overall economic data.

We can also look at the tools, which have improved relatively quickly but don't appear to be improving exponentially. GPT-4 and GPT-4o came out about a year after their predecessors. Is GPT-4o a bigger leap that GPT-4 was? Are GPT-4.5 or 4.1 a bigger leap than GPT-4 was? I honestly don't know, but the general reception suggests otherwise. The biggest leaps recently seem to be making models that perform roughly as well as past ones but are much smaller. That has advantages from the standpoint of democratization and energy consumption, but those kinds of improvements seems to favor a situation where AI augments workers rather than replaces them.
