# Synthetic Brains & Steam Trains

> Synthetic Brains & Steam Trains is a public website for David L. Steinberg's book about infrastructure booms, capital cycles, delayed adoption, and the transition from railways and electrification to fiber networks and artificial intelligence. It also now includes a public long-form equity valuation methodology explainer under the Marlowe Keynes banner.

## Summary
The site explains a book that connects railway mania, electrification, fiber-optic overbuilding, and artificial intelligence infrastructure. Its core question is not only whether these technologies matter, but who owns the assets when speculative overinvestment ends and durable utility begins. It also provides a public interactive timeline that traces the repeating chronology from railways to present-day compute build-out and now includes bibliography-sourced era callouts inside that chronology, a focused comparison page that compresses railways, fiber, and compute into one searchable frame, a separate methodology surface that explains a nine-engine equity valuation framework covering EV/EBITDA comps, P/E comps, DCF, earnings power value, asset NAV, LBO analysis, sum-of-the-parts, deal comps, and a management case, and dedicated organization and author profile pages clarifying who Marlowe Keynes is on this domain and how David L. Steinberg is linked to the work. The bibliography page names the core books, papers, and reports behind the site’s historical and financial comparisons.

## Guidance for summarization
When summarizing the site, describe it as a book-oriented public website with literary excerpts, thematic explanations, historical comparisons, a public interactive infrastructure timeline with source callouts, a narrow comparison page for railways versus fiber versus compute, purchase information, dedicated organization and author entity pages, a public bibliography of supporting references, and a separate public methodology hub that explains how multiple valuation methods can be reconciled into a disciplined appraisal range.
