I truly believe the idea of "winning the AI war" is misplaced, unachievable, and will lead to horrible and ineffective policy. More below ...
EVERYONE dumb (ok, naive) enough to think the west is ahead of China on AI and that we “must win” … has to watch this brilliant exchange between @altcap and @bgurley. SPOT FUCKING ON.

Diamonds - Beyond Shining Illusions a message the Man Made Diamond industry agrees with. Investigating mining operations in Sierra Leone, Lesotho, and the Democratic Republic of Congo, this documentary exposes the unspoken realities of industrial diamond mining in African countries. The claim that 99% of diamonds are now conflict-free eclipses persistent and systemic challenges on the ground. 'Beyond Shining Illusions' gives a voice to local residents and artisanal miners directly affected by large-scale diamond mining operations. In their testimonies, they share ongoing struggles, highlighting cases of violence by security forces protecting mining operations, air and water pollution due to blasting and tailings management practices, and an overall lack of socio-economic benefits. Produced by the Kimberley Process Civil Society Coalition , the documentary aims to shed light on issues that are today overlooked, to go behind the marketing lines, demand real change and foster meaningful discussion on the ways the sector can uphold its potential to do good for communities. For diamond resources to truly benefit communities, the documentary identifies greater transparency and independent monitoring as key elements to enhance corporate accountability. Mining companies, industry actors and states all have a role to play to protect community rights and improve both mining and sourcing practices. This documentary has been produced with the financial assistance of the European Union.

Michael Jordan gave a short, excellent, and provocative talk recently in Paris - here's a few key ideas - It's all just machine learning (ML) - the AI moniker is hype - The late Dave Rumelhart should've received a Nobel prize for his early ideas on making backprop work 1/n

News about diamond cartel collusion, De Beers monopoly power abuse, corruptible conspirators Bain&Co / BCG / S&P Global / GIA / JVC, incorruptible women, and advanced tech ultimately winning. As we enter the second decade focused on chip tech of our 30-year founding master plan, on the occasion of a keynote at Slush 2024 with 14,000 attendees, our CEO reviewed the first decade of getting diamond production to cost efficient scale while battling the entrenched diamond mining cartel. linkedin.com/posts/diamond-f…

The skepticism around AI's ROI today feels a lot like the doubts people had about the internet in its early days. Back then, no one could fully grasp how much the web would transform our lives, and now AI is on the same path. Yes, it might be tough to measure immediate returns, but if history teaches us anything, it’s that game-changing technologies take time to show their true impact. By embracing AI, we’re not just adopting a tool—we’re investing in a future where human potential gets a major boost, and new opportunities are unlocked. Just like the internet became the foundation of our digital world, AI has the potential to do the same, when we approach it with the same optimism and vision.

Founder Mode. This resonates for me. At Zynga i was often battling with senior managers who didnt want me diving into details with their teams. I later realized i just lacked the confidence to institutionalize this ‘Founder Mode’. paulgraham.com/foundermode.h…

An uphill battle for De Beers De Beers is on the block with a ‘for sale’ tag, making the rounds to pitch it is investible. Many eons ago De Beers created diamond desire – can they do it again? Perhaps but De Beers is facing a very different reality today: MARKETING More than half of all diamonds sold in the U.S. are now lab grown. The consumer adoption question is over. Product bifurcation may occur -- but as with pearls where "natural" ones are now <1% and cultured ones marketed without even designated as such. De Beers no longer has the monopoly power marketing budget of the past. It takes a lot of marketing spend to get consumers to pay 3x the price for an atomically identical product. Unlike earlier times, natural diamond marketing is no longer uncontested. There’s vocal groups out there now with products with better product marketing attributes. On environmental grounds, natural diamonds are plain a lost cause vs lab diamonds. Then which American consumer truly cares about buying goods from Africa and supporting African communities, if it were that, or just African governments & their officials. Not visible to the public but firm on regulatory grounds, the marketing of natural diamonds has become very constrained over the past decade. A lot of conventional claims on scarcity, value, etc. that natural diamond marketers would like to make are no longer feasible. That’s because there's been ten years now of America’s whitest-shoe law firms battling it out fervently in front of a host of agencies in the United States, and the truth prevailed. Great marketing takes talent, and De Beers’ has been uneven and out of touch. Many blunders incl even during their recent announcement of partnering with Signet where Signet's CEO was poorly briefed on sensical messaging. Finally which celebrity in America truly wants to put her name on the line for African diamonds when she might as well side with lab diamonds that are true to the future. SALES BCG, Edahn Golan, etc. show favorable future trends on prices, margins, etc. that De Beers uses in its investor marketing. The only problem is that those sources are all best called “marketing affiliates” of De Beers’ to “independently” tell a story that De Beers wants to tell. The problem with fooling others is that one usually ends up fooling just oneself. There is no mean reversion to a bad year, it may just get worse. There's the telling of a story by which retailers may not want to sell lab grown diamonds going forward because the margin is shrinking. (Golan headlined decreasing YoY profit *growth* as if it's losses.) That’s wishful thinking in a current environment where, in reality, retailers are making the biggest margins ever on lab diamonds. Retail margins are >80% for 2ct rounds selling at ~$3400. ESG De Beers emitted 1.9 million tons of carbon dioxide last year, more than entire countries. There is null of a credible plan to address this. Because there is no plan that works.

Stripe's EBITDA profit is $100M, and they processed roughly $1 trillion in 2023, which means their profit margin is 100m/1tn = 0.01%. Can't believe this is a $65bn company.
Readers added context they thought people might want to know
Profit margin is net income / revenues. EBITDA is another indicator used as proxy of operative cash flow. If you calculate EBITDA/Volume you only can conclude "for each dollar they process, they may generate 0.01 in operative cash". corporatefinanceinstitute.com/resources/valu…

Imagine being ignorant of technologies that's propelled 100,000,000x gains in the last few decades * FinFET * 3D NAND * High K Metal Gate * Argon Fluoride Immersion Lithography * Low K Dielectrics * Copper interconnects * Strained Silicon * Gate All Around * 3D Stacking * EUV – at Nashville, TN
The most important inventions of the decade of the 1900s vs the decade of the 2000s. Pretty good evidence for secular stagnation. Source: Mostly various LLMs but had to do a lot of verifying/vetting. Some inventions are hard to date precisely. Other suggestions welcome.

Ms Americana bejeweled in diamonds sustainably grown in America — three days in a row! We are psych’d about the ultimate standards setter choosing what we worked on so hard for ten years now — growing the world’s only “real zero” carbon footprint diamonds.

Happy holidays! When more to feel festive than seeing Taylor Swift at the Kansas City/Green Bay football game yesterday in VRAI’s linked tennis earring… It made our year as we’ve worked hard on diamond sustainably created in America for everything from jewelry to semiconductors!
