Ideally, they would also explain why they think this even if the evidence is relatively illegible or some of it needs to be redacted.
Insofar as Anthropic thinks the survey is mostly capturing vibes in a way that doesn't depend much on the operationalization in the survey, this seems important to note.
Ideally some third party would instead do surveys, interviews of employees, managers, and or leadership and these results would be reported.
It seems like Anthropic isn't that interested in doing carefully done surveys, fair enough.
And it would be useful to standardize this across AI companies.
I do think it would be possible for Anthropic to collect information or do surveys that do shed light on this question.
I'd be most interested in a survey of the views of employees for whom we're very confident that employee has a detailed understanding of exactly what is meant by different uplift notions and is interested in AI forecasting.
I'm much more interested in capturing the views of employees who have thought a decent amount about this than capturing an unbiased sample.
It would also be possible to do more qualitative and quantitative data collection from various employees and then convert this into acceleration estimates taking into account things like people using AIs to do low-value tasks they wouldn't have done otherwise.
That's the end of the list.
If there is a large disagreement about the current level of uplift, this seems like a particularly tractable empirical crux.
I would substantially shorten my timelines if I learned the uplift was much higher than I expect and I guess some people at Anthropic would lengthen theirs if they learned it was significantly lower than they expect.
I also expect that various people who are much more skeptical than me of reaching very high levels of AI capability within the next 10 years would update some on credible internal uplift measurements.
Getting better empirical information about the level of uplift seems hard but doable.
Additionally, Anthropic claims, we estimate that reaching two times on overall progress via this channel would require uplift roughly an order of magnitude larger than what we observe.
Insofar as productivity uplift is supposed to correspond to something like serial labour acceleration, I'm very sceptical.
I think roughly 40x serial labour acceleration would yield much more than 2x faster progress.
My guess, see the appendix.
Estimating AI progress speed up from serial labor acceleration is that you'd get 2x overall AI progress at around 5x serial labor acceleration.
My understanding is that the AI futures project timelines model would indicate that around 8x serial labor acceleration is required.
