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: Take an Art Break

The best way I know to keep complex work in perspective is to stop at intervals and look at something that took the same order of sustained attention under real constraints. The studies now show what that does: a museum visit restored attention where an urban walk did not, judging the beauty of an object raised abstract thinking almost 14 per cent, and artistic film raised originality even in people who felt worse for it. Five works, Leonardo to Holbein, and the non-default decision in each.

Tokenisation and RWA With KXCO: ML-DSA-87 on Chain, Verifiable by Anyone

Armature, KXCO's chain, has verified ML-DSA-87, the highest security category in NIST FIPS 204, natively on chain since 6 October 2026, and KXCO's platform signing keys moved to it on 6 and 7 October. Regulators now name tokenisation a supervisory priority, and DORA already requires cryptography that can change with cryptanalysis. Six tests an institution should run before it trusts a tokenisation platform, and where to check KXCO's answer to each.
