What AI bosses overstate is often the jump from capability to dependable responsibility. This is my interpretation of the evidence, not proof of bad faith.

METR revisited its widely repeated early 2025 result in which experienced developers were 19 percent slower with AI tools.
What it does not prove
Later results were affected by selection bias. METR says greater acceleration is likely, but cannot quantify it reliably. The earlier figure is not a current universal result.
My operating rule
Keep the measurement date, task population and uncertainty attached to every productivity number.
Anthropic analysed selected tasks in November 2025 conversations and estimated task success with Claude-classified interactions and human feedback loops.
What it does not prove
Those estimates are not independently audited business outcomes. A task can be completed while the surrounding commercial process still fails.
My operating rule
Trace accepted work through its handoffs, exceptions and final human decision.
The claim. Dario Amodei wrote that powerful AI could arrive as early as 2026, while allowing that it could take longer, and explored decades of biological progress compressed into years after that point.
The limit. The essay presents an explicitly speculative scenario. Its qualifications matter as much as its most dramatic numbers.
Operating rule. Treat forecasts as planning inputs, never as proof that a capability is dependable today.
