Diffusion - The Capability Frontier (B4, B8, B9, B12)#
Contents
The leading edge: how long agents run unsupervised, whether the verifiable/unverifiable gap holds, whether the research loop itself compresses, and whether any of it reaches atoms. These four are the family's earliest movers and its most demo-contaminated - every entry insists on production deployment over demonstration for exactly that reason.
B4 - Agent reliability#
| Baseline | Reliable on short, verifiable, well-scoped tasks; degrades sharply with horizon |
| Trigger - the transition lands | Multi-hour autonomous task completion at >90% success without human checkpoints, in production |
| Trigger - plateau | Horizon length stalls for >18 months despite capability gains elsewhere |
| Revises | 2026–2028, Software, Part V row 1 |
Measure task horizon at fixed reliability, not benchmark scores. The economically relevant question is never "can it do this" but "can it do this unsupervised for four hours without a failure that costs more than the labor saved." Those diverge, and the second is what firms actually buy.
Contamination to refuse. Demo videos, supervised "agent" product tours, and benchmark suites with hidden retry budgets do not move this indicator. Prefer: production incident rates, human-handoff frequency per task-hour, and whether the buyer removed the checkpoint after a measured pilot rather than as a launch claim.
B8 - Verifiable vs unverifiable domain gap#
| Baseline | Large gap: software/math/code far ahead of open-ended professional judgment and physical manipulation |
| Trigger - asymmetry holds | Gap stable or widening as measured by production deployment depth (not demos) |
| Trigger - asymmetry fails | Production autonomous decision-making in liability-bearing unverifiable domains without cheap external ground truth |
| Revises | Uncertainty 5, Steelman §1, ordering of Part III |
Pair with insurance and liability: if underwriters cover autonomous professional judgment, they are revealing a belief that verification is solved enough to price.
Gap construction. Prefer production deployment depth (share of workflow run without human sign-off in liability-bearing settings) over capability evals. A model that writes strong legal strategy memos in a lab eval but cannot be the final signer does not close the gap. Closing requires the institutional stack - licensure, liability, insurance - to accept the output, which is why this indicator is coupled to C6 and Uncertainty 5's institutional cushion.
B9 - Research cycle time (RSI governor panel)#
| Baseline | Not disclosed; infer from release cadence, paper throughput, and hiring of research engineers |
| Trigger - technical loop | Sustained >2× compression in time per validated experiment at frontier labs |
| Physical governor check | Cycle compression coexists with queued power/fabs - capability not deployable at the new rate |
| Financial governor check | Cycle compression coexists with rising real hurdle rates on training clusters (A7) |
| Revises | Uncertainty 1 - all three governors, not only the technical one |
Headline RSI talk tracks only the first row. The document's revision in round 7 requires reading all three before moving timelines. Compression with either governor binding is a local technical win that does not pull Part IV forward until the governors clear.
B12 - Physical diffusion (atoms, not demos)#
| Baseline | Warehouse/port autonomy rising but teleop-heavy; specialty harvest still human; hub-to-hub driver-out freight pilot-scale, multi-state insurance incomplete |
| Cadence | Quarterly industry reports + regulator filings |
| Trigger - warehouse path | Autonomy share of unstructured warehouse pick tasks crosses ~50% (not sortation alone) |
| Trigger - freight path | Driver-out hub-to-hub commercial service on major US corridors with published insurance (not geofenced pilots only) |
| Trigger - harvest path | Specialty crop harvest robots at delivered $/hour competitive with local wage at scale (not demos) |
| Trigger - lag confirms | Through 2032, structured environments commercial while last-metre and specialty harvest still labor-bound |
| Revises | Robotics, Logistics, Agriculture, 2032–2040, Part V row 5 |
This is the III.B companion to the headline teleoperation ratio. Prefer delivered work metrics and insurance-enabled routes over unit sales. Structured-first is the base case; early unstructured success pulls the growth fork forward.
Secondary: port automation share by region (geopolitical capacity); farmland equipment autonomy miles.
B4 × B12 is the fork#
Agents that clear multi-hour verifiable cognitive work (B4) without physical diffusion (B12) confirm the cognitive/physical split - high Part V row 1, low row 5 pressure. Both firing early is the high-growth branch of 2032–2040. B12 without B4 is unlikely under this framework (atoms harder than symbols); if observed, re-check measurement contamination on B12 first.
