Some kind of quantitative estimate of the effects on the effective pool of cognitive labour would be good.

If an H100 equivalent (part of a cluster running the latest public models) has roughly the cognitive capability of a junior engineer, and the capacity of ten of them (runs 5x as fast, for twice as long per day), then 16M H100e is a workforce increment of 160M CS grads. Next year that could be 1600M. But that "10x a CS grad" figure could be 100x too large or 10x too small, I don't know. (And I know I don't know enough to estimate it.)

(Of course over 90% of capacity is currently used for training next-gen models rather than inference, but the principle holds.)

Riffing off Dario's "country of geniuses in a data center": barring disasters, the early visible effects of AI will come from a continent of college grads in a thousand data centers. How big is that continent? Australia (30M people) or Asia (5,000M people)?

Agreed that this is _very_ hard to estimate... and in any case the ratio of human to AI productivity can't be expressed in a single number. Reason #17 (of 99999) that the future is hard to predict.

My understanding is that the percentage of frontier lab compute devoted to R&D is closer to 50% than 90%? Something like (_very_ handwavy): 10% for the training run that produces the next shipping model, 40% for other R&D activities (experiments, failed training runs, etc.), and 50% for serving customers. I don't have a specific source offhand, but to the best of my recollection, the 50/50 split is consistent with occasional reports on finances at OpenAI / Anthropic, and I've seen comments from researchers that most of the R&D compute is used for things other than final training runs. Do you have a source for the R&D share being closer to 90%?

No, only an off-hand comment by Zvi.

Edit: yes, AIUI over half the R&D is not directly training, but it is testing and otherwise making the next gen fit for purpose, so not available for customers to use.
