"assessment": "The claim is that AI systems taking over a growing share, but not all, of the tasks in AI research and engineering will markedly accelerate progress in AI software before AI R&D is fully automated. The theoretical case is that humans can concentrate on the tasks AI cannot yet do while AI handles the rest, so speedups compound well before the last task falls; the counter-case is that the slowest, human-only tasks and compute limits bottleneck overall progress, so partial automation yields modest gains until automation is nearly complete.\n\nThe most direct 2026 evidence favours the claim. METR's high-access assessment at Anthropic (November 2026) found that benchmark capabilities of Anthropic's models (on Anthropic's version of the Epoch Capabilities Index) have grown about 1.9 times faster since October 2025 than before (95% interval 1.5 to 2.8), that this was not caused by faster growth in training compute, that a majority of the acceleration is likely attributable to AI use in R&D, and that the acceleration comes mainly from AI assistance rather than fully autonomous contributions. That is a substantial speedup arising from partial, not full, automation, and METR reports no strong bottleneck yet in view.\n\nThe evidence has real limits. It covers one developer; much of the most informative evidence was redacted, so the public must take METR's judgment on trust; the benchmark-based measure may overstate progress on less well-specified tasks or reflect benchmark artifacts; and attribution to AI rather than other factors is uncertain. Controlled measurements of individual productivity are more mixed: METR's 2025 trial found experienced open-source developers about 19% slower with AI tools, and its 2026 follow-up was judged unreliable because of selection effects. Organisational-level acceleration and individual task-level uplift measure different things, and the former bears more directly on this claim. On balance the claim is supported, with credence around 0.7; replication at other labs and published, unredacted data would most move the verdict.",

"reasoning_trace": "Own model first: under a CES-style task model, partial automation gives large speedups only if human-only tasks are substitutable or the automated share is high; strong complementarity (Baumol bottlenecks, experiment compute) would cap gains. So the claim is an empirical question about the elasticity and current automated share; the best evidence is organisation-level measurement of progress rate attributable to AI.\n\nEvidence read: METR, \"Independent Assessment of AI R&D Acceleration at Anthropic in October 2026\" (https://metr.org/blog/2026-11-05-anthropic-ai-rd-acceleration-assessment/): AECI trend 1.9x [1.5-2.8x] since Oct 2025; not explained by training-compute scaling; majority likely attributable to AI use; primarily AI assistance rather than autonomous contribution; no significant bottlenecks seen for next 12 months but low confidence; majority of most informative evidence redacted by Anthropic (evidence not shown; Anthropic has an interest in how its R&D progress is portrayed, though METR is the examiner). METR flags possible overestimation (non-AI factors, verifiable-task focus of AECI, unusually low early baseline) and underestimation. Counter-evidence: METR 2025 RCT (-19% speed for experienced OSS developers) and METR Feb 2026 update (https://metr.org/blog/2026-02-24-uplift-update/) saying the redesign was forced by selection effects, with original-cohort estimate -18% (CI -38% to +9%, sign convention debated). International AI Safety Report 2026 describes expert disagreement. Forethought's essay (source instance) advances the theoretical reallocation argument. Not decomposed further this pass for budget reasons; key cruxes are (a) whether the Anthropic acceleration is real and AI-caused, (b) whether it generalizes beyond one lab and beyond well-specified tasks, (c) whether bottlenecks emerge."
