Don’t be the best.Be the only.

A distinct human presence is becoming scarce.

Veni, vidi, cogitavi

Every financial revolution has changed the speed and the surface of finance without changing its substance. Debt cycles still overshoot. Inflation still compounds. Bubbles still form around the new thing while the old rules keep applying. What is different this time is that intelligence itself has become abundant, and everything abundant gets cheap. The scarce thing now is a distinct human presence: judgement shaped by real consequence, taste built over decades, and the willingness to care about a question for longer than is efficient.

I write about that gap most days, and I build in it the rest of the time. Forty years across capital markets, venture capital and emerging technology, and the part that still cannot be automated is the judgement about which question was worth asking. Everything below is published at Live Trading News, wrapped in post-quantum cryptography and anchored on chain at the moment it goes out. The text cannot be altered. Change a word and it is re-signed and re-stamped, and the chain records the new time, so every version and every date stands permanently on the record.

AI

The build-out, the quantum timeline, and what any of it is actually for.

Thinking

Judgement, independence, and staying non-fungible in an AI world.

Markets

Stocks, macro, ramblings and the KXCO build.

Longevity

Healthspan science, and separating the evidence from the sales pitch.

Life

Food, travel, sport, and the unoptimised parts that refill the well.

Thoughts on Thinking: You Are the Data Centre

The world's data centres used about 485 terawatt-hours of electricity in 2025; the brain runs on about 20 watts. The adult male brain holds about 86 billion neurons on average, and its synapse weights at 32-bit precision take at least 400 terabytes. Against the eye's estimated output, GPU memory wins on raw throughput by millions to one, but meaning needs selection, context and consequence. At KXCO the person sits at both ends of the data, and a named person decides.

The Week Ahead on Wall Street, 9 November 2026: AI Is Still a Buy

We still think AI is a buy. After the midterms the semiconductor index fell 11.4% while the S&P 500 lost 2.5%, in our view an overreaction that fell on the chip names. October payrolls rose 165,000, oil stays high with the Iran war unresolved, Alibaba and Tencent gained, NVIDIA trades at 15.4 times forward earnings, and both SpaceX and Tesla have special committees studying a combination. KXCO's AI ontology shows the relationships behind the NVIDIA, China and SpaceX calls.

Thoughts on Thinking: Brain Chemistry

Brain chemistry sets the level of thinking and of performance in everything else, and it bears on longevity: 14 risk factors that can be changed account for nearly half of dementia cases. The dangers come from outside, through plastic, PFAS, pesticides and metals, and from inside, through chronic stress and overwork. An organic diet cut a chlorpyrifos marker in urine by 60.7 per cent, and reciting the rosary slowed breathing to under six breaths a minute. The chemistry is a managed input.

San Luigi dei Francesi: Artworks and History

An LTN art break, away from the midterm noise. San Luigi dei Francesi, France's national church in Rome, holds Caravaggio's first public commission: the Calling, the Martyrdom and the Inspiration of Saint Matthew, painted from 1599 to 1602. Shayne Heffernan on the church since 1478, the chapel's long wait for Caravaggio, the altarpiece Rome refused, and the church's place in the history of the Catholic Church, with four knowledge graphs and links to the full-resolution scans.

Crony Capitalism: The Force Destroying Western Civilisation

Western civilisation is being dismantled from the top, Shayne Heffernan argues, by a crony capitalism that picks winners through capital, regulation and the Fed. The top 1% of US households hold 32.5% of net worth, up from 22.9% in 1990, while the 50th to 90th percentiles fell from 36.1% to 28.8%. Insured banks fell from 17,901 in 1984 to 4,238 in 2026, listings have halved since 1996, and the median first-time buyer is 40 by the realtors' count. His fix: radical transparency and openness.

Democrats' AI Spending Curtailment: The Dumbest Idea in Washington

After the midterm sweep, Democrats want to slow America's AI build-out. The Sanders and Ocasio-Cortez bill would freeze building and upgrading of AI data centres nationwide, and a superintelligence ban Rep. Yassamin Ansari wants atop the agenda would pause every model trained with 10^25 operations or more. Governors-elect in Texas and Georgia back pauses, and Goldman Sachs puts 45% of planned capacity in Democrat-run states backing moratoriums. Shayne Heffernan: AI computing follows the power.
