AI Bashing

20 Nov 2025
Artificial intelligence is everywhere, whether whispering through Main Street or roaring across Wall Street, as evidenced by Wednesday’s Nvidia earnings release. And with its rise comes a wave of critics saying the whole thing is a bubble on the verge of bursting, threatening to take trillions in investments down with it. But is this really insight, or just another round of AI bashing, asks Didier.

Gold Miners
Gold prices have pulled back over the last two weeks and yet the macro conditions that pushed them higher remain largely in place. In this piece, Didier assesses the fundamental case for gold through the lens of gold-miner plays.
Price Is What You Pay, Value Is What You Get
The intrinsic value of any asset is related to the notion of either scarcity or efficiency, and sometimes both together. Didier uses this analytical framing to consider the current value proposition of the world’s most liquid asset classes— those constantly subject to price adjustment—namely government debt, publicly-listed equities and gold.
The S&P 500 Gini Index
The well-known Gini coefficient measures income inequality on a scale from 0% to 100%. In this note, Didier calculates an S&P 500 Gini index for market capitalization, and finds that the concentration of market cap among a few giant names is reaching what may well be its upper limit. However, a rebalancing need not be bad news for investors.
The Currencies Of Bridge-Builders
In an age of increased great power competition, Didier investigates the reasons for the recent outperformance of the currencies of non-aligned countries that have taken care to steer a mid-course between the world’s big players.
Is The Gold Rally Normal?
Since the collapse of the Bretton Woods monetary system in the early 1970s, gold has experienced four major bull markets. Didier and Michael say when you align each rally from its starting point, today’s surge looks tame next to the explosions of the 1970s, but almost identical to the steady climb between 2001 and 2012.
Power Is When You Have It
In 2008, French senator Maurice Faure—signatory of the Treaty of Rome—was asked: what is power? His reply was disarmingly simple: “Power is when you have it.” No hedging, no abstractions. The same could be said of beauty, youth, strength—and of a nation or its currency. In this report, Didier explores the concept of ultimate power as expressed through financial asset pricing.
