How fast the future is arriving, by the numbers.
A free, rigorously documented set of indices tracking leading indicators across AI, compute, and energy. Built from public data. Reproducible methodology. No forecasts — only measurements.
This week
Source: arXiv API. Query: (cat:cs.AI OR cat:cs.LG) AND submittedDate:[month]. Raw CSV · Methodology
Our commitments
- No forecasts. Every published claim is a measurement or a description of one.
- Numbers come from public APIs, never from an LLM. Editorial prose may be AI-assisted; numbers and charts are deterministic.
- Every number is traceable in three clicks — brief, canonical CSV, source methodology.
- Methodology is versioned. When a query changes, the version bumps and old values stay verifiable in git history.
- Sponsors never appear above the editorial. One sponsor per brief, never programmatic, never hidden.
- Subscriber data is never shared or sold — not to sponsors, not in aggregate, not for any reason.

Indices
-
arXiv AI research velocity
Monthly count of papers submitted to cs.AI or cs.LG — the raw expansion rate of the AI/ML research surface area.
-
Global compute capex
Combined capital expenditure on semiconductor fab and hyperscaler data center buildout, from public disclosures.
-
Battery $/kWh
Unsubsidized lithium-ion battery pack price tracked against historical trajectory.
An index is never announced as "coming by date X" — we list it here only once the methodology is drafted and the pipeline is real.
