# Erik Brynjolfsson

## Profile

MIT economist studying digital productivity and AI's macroeconomic impact.

## Role in This Source

Cited via a Financial Times piece in which Brynjolfsson notes that **US productivity grew roughly 2.7% in 2025 — about double the decade average** — and attributes a fair share of that surge to AI and AI agents.

The speaker uses this as macro-level evidence that the productivity payoff from agentic AI is real and already showing up in aggregate numbers — strengthening the urgency of building infrastructure (a [[concept-open-brain-d22]]) that lets *individuals* capture that payoff rather than leaking it to context-switching costs (see [[claim-context-switching-devastating]]).

## Note on Verification

The enrichment overlay flags that the exact quote was not independently verified, though the date and Brynjolfsson's research focus make the framing plausible.
