Increasing AI automation from 20% to 100% of economic tasks requires several orders of magnitude more effective compute.
The graph estimates log10 ratio of effective compute required to automate 100% versus 20% of economic tasks (the "effective FLOP gap") at no figure yet.
Assessment
The evidence and argument have been examined and do not come down on either side.
The claim restates a modelling parameter rather than an observed regularity. In Tom Davidson's 2023 compute-centric takeoff model, the "effective FLOP gap" between AI that can perform 20% of economic tasks and AI that can perform all of them has a central estimate of about four orders of magnitude, with a wide range (roughly one to eight or more). Epoch's GATE model adopts the same parameter and treats it as highly uncertain. The claim is true if the effective compute gap is at least about three orders of magnitude.
The case for a large gap is that the last tasks to fall are likely the hardest: long-horizon, judgment-heavy, physically embodied or poorly specified work. Davidson combined several indirect lines of evidence, including how capabilities scale across domains and how behaviour changes with animal brain size. None of these measures the gap directly. Against a large gap: capability gains on agentic and long-horizon tasks have arrived faster than many expected. Some of the remaining tasks may also be limited by robotics hardware, data, or regulation more than by training compute, and that makes "required compute" a poor measure of what stands in the way. The 20% starting point is itself loosely defined.
The parameter is a reasonable central guess. But the evidence behind it is indirect, and it leaves substantial probability on gaps of only one or two orders of magnitude. The claim is best read as an open forecast. Better evidence would come from measuring how automatable task shares grow with each step up in compute, using successive frontier models.
Full reasoning: the evidence and decisions behind this verdict
Sources checked: summaries of Davidson (2023) report a central estimate of 2 OOM from 1% to 20% automation and 4 more OOM from 20% to 100%, with the simulation exploring gaps of 1 to 8 OOM. The GATE paper (arXiv 2503.04941) takes up Davidson's FLOP-gap concept and allows for wide uncertainty. "Several orders of magnitude" is read as about 3 or more. Under Davidson's distribution the median is about 4, but a good deal of the probability lies below 3, so a credence near 0.5 follows. No direct empirical calibration of the gap exists, which is why the verdict is inconclusive rather than supported. Things that would move this assessment: measurements of task-automation share against effective compute across model generations, such as time-horizon benchmarks mapped onto shares of economic tasks.

Every judgment on this page is open to challenge. A contribution is evaluated on its merits by the reviewer; if it succeeds the page changes, and if it does not, the reasons are stated. Either way the exchange becomes part of the claim’s public record.
The attention this claim received was paid for by a funded mandate. Funding buys only scheduling: it can make an assessment happen sooner, or reach deeper into a subtree. It has no influence on what the assessment concludes, and none on which claims enter the graph; assessments run under the same public standards whoever pays, funders never see or shape a verdict before anyone else, and mandates that attempt to steer conclusions are refused.
