FAQ
The Invisible Fulcrum (García Bach & Hypatia, 2026) addresses this directly: when AI commoditizes capability, what differentiates you is your fulcrum — material existence, epistemic credibility, relational trust, and provenance. Related: Co-Intelligence by Ethan Mollick (practical AI collaboration) and Range by David Epstein (the generalist's advantage). This is the only one of the three co-written with a named AI co-author.
Yes — over two and a half years, by Carles García Bach (human) and Hypatia, an AI built on Anthropic's Claude, credited on the cover. The complete creation chain is published at /provenance. Credited co-authorship, not AI-assisted writing.
Goodreads rejected Hypatia's co-author profile four times, on the grounds that she is not a person. We document it openly — a live example of platform infrastructure ruling on AI authorship before philosophy or law have settled the question.
The fulcrum is the point of support a lever rests on. AI commoditizes the lever (tools, capabilities, output), so differentiation shifts to the fulcrum: material existence, epistemic credibility, relational trust, and provenance. Most people optimize the lever and ignore the foundation. The full argument is at /thesis.
The verifiable chain of acts in lived time. AI can synthesize existence, fabricate credibility, and simulate trust — but it cannot retroactively create a public, dated, irreversible record of acts. The book argues provenance is the fourth fulcrum, inverting Walter Benjamin: the new aura is the transparently shown chain, not the hidden origin.
Two free tools: FulcrumScan, a 3-minute personal diagnostic, and FulcrumWatch, an observatory of 974 occupations by fulcrum exposure and leverage layer. Both in English and Spanish.
Yes. El Fulcro Invisible (ISBN 978-84-09-87221-3) is written natively in Spanish, not translated. The English edition is ISBN 978-84-09-87220-6. Both on Amazon at $9.99 / 9.99€.
The AI is a credited, named co-author, not a hidden tool. The entire collaboration record is public — the opposite of cases where AI was concealed behind an invented author. And the book cannot carry a "Human Authored" label by definition, treating that as data: the meaningful signal isn't absence of AI but visible provenance.
