The $25,000 Mistake AI Just Made ObsoleteVIEW IN BROWSER | FOLLOW LUKE ON 𝕏
California Steel Industries’ Hot Strip Mill in Fontana stretches more than half a mile long. Inside, giant ovens heat steel slabs to about 2,300 degrees Fahrenheit. At that temperature, the steel gets soft enough to roll. But first, it needs cleaning. The furnace leaves a thick crust of “scale” on the surface. If it isn’t removed, it gets pressed into the steel and ruins the finish. A scalebreaker cracks the crust loose. Then high-pressure water jets blast it away. Next, the steel slab passes through five roughing stands that squeeze it down from between 7 and 9 inches thick to as little as 0.0538 inches — close to the thickness of a credit card. A crop shear trims the ragged ends before the steel moves to finishing. Then six more finishing stands roll it to its final thickness and surface quality. By this point, the steel is moving at about 35 miles per hour. That’s too fast to catch defects by eye. For automotive panels and appliances, the surface has to be flawless — defects show right through the paint. The finished strip winds into a coil. Some weigh up to 25 tons. The whole process takes about five hours. At full capacity, the mill runs 24 hours a day and produces 2 million tons of steel per year. But at least you can see steel. In today’s most advanced semiconductor fabrication plants, the defects that matter are invisible to the human eye. And the consequences of missing them are just as severe. A Single Semiconductor Defect Can Cost $25,000 — and Human Inspectors Can’t Stop It
In semiconductor manufacturing, everything starts with a wafer — a thin, polished disc sliced from pure silicon, usually about 12 inches across. These wafers must be flawless. Even a microscopic scratch or contaminant can create defects across hundreds of chips. The first step is circuit printing using extreme ultraviolet lithography. This process projects circuit patterns using light with a wavelength shorter than any visible color. A single finished chip can require 20 to 30 passes through this stage alone. The specialized masks used in this process — a kind of three-dimensional stencil — have to be perfect, too. A single defect ruins every chip that mask touches. And those masks can cost up to $1 million each. After each pass, the wafer goes through etching, deposition, and chemical treatment to build up transistor layers. Then the cycle repeats. Today’s most complex chips go through 1,500 to 2,000 individual steps before they become functional. Each step is a potential failure point. One particle of dust can ruin an entire wafer. A single wafer for the most advanced semiconductors can cost between $20,000 and $25,000. Each wafer holds hundreds of chips. A defective one wipes out hundreds of products at once. And the fabs where all this happens cost between $15 billion and $20 billion to build. Fabs need to reduce these losses wherever possible. And human inspectors simply can’t do the job. At 35 miles per hour, steel moves too fast to see. In a semiconductor fab, the defects are too small to see. In both cases, the stakes are too high to miss anything.

Goldman Sachs, JPMorgan, and Blackstone are buzzing with a new kind of trade. It’s not the Mag 7. It’s not crypto or gold. Instead, it’s a new kind of asset class that’s already attracting piles of cash from some of the richest investors in history — Gates, Thiel, Bezos, Gates, and Altman. If you’re smart, you’ll mirror that trade. This new free video from two of our top analysts shows you how. |

AI Is Boosting Quality ControlThis is one area where AI doesn't just help. It’s the only solution that actually works. AI “deep learning” and “edge learning” take defect control to a level humans can’t match. Deep learning works by analyzing hundreds of example images until the system learns to make decisions on its own — no programmer required at each step. Edge learning goes further. These systems come pretrained and may need as few as five to 10 images to get started. They deploy in minutes. The results are measurable. At BMW, AI-powered vision systems cut defect rates by 30% at one European plant within a year. Customer satisfaction jumped 15% after the rollout. At Foxconn, AI-powered cameras now catch defects with 98% accuracy, flag 80% fewer false alarms, and inspect each unit 60% faster than before. These aren’t pilot programs. They’re production systems running at scale, in some of the most demanding manufacturing environments on Earth. This is what I mean when I say the real AI story isn’t the one getting the most attention. Everyone is watching the big infrastructure names — the chip companies, the cloud providers, the chatbot platforms. And yes, those are important. But there’s a parallel story playing out on the factory floor, in the oil field, and in the semiconductor fab. AI is solving problems that weren’t solvable before. And the companies delivering those solutions are becoming more competitive, more profitable, and more valuable — quietly, without much fanfare. That’s exactly the kind of opportunity I’ve spent my career looking for. Finding the Next Generation of Winners Before the Market Catches OnThe challenge, of course, is identifying which companies are actually winning — not just claiming to use AI, but using it in ways that show up in the fundamentals. That’s a problem Marc Chaikin has been working on his entire career. His Power Gauge rating system was built to cut through the noise and find stocks with real momentum behind them. It’s been doing that for decades. But on June 24, Marc and I are going a step further. We’re unveiling the first AI-powered product Chaikin Analytics has ever built — and it’s unlike anything we’ve shown the public before. We’re calling it the Time Machine. It scans decades of market history to find stocks today whose fundamental and technical fingerprints match the early profiles of stocks like Nvidia Corp. (NVDA), Amazon.com Inc. (AMZN), and Meta Platforms Inc. (META) — right before they made their biggest moves. In backtesting, it surfaced stocks that went on to deliver gains of 995%, 1,406%, and 3,804%, all while the “seed” stocks they were matched against posted far more modest returns. The factory-floor AI story is one example of the kinds of opportunities the Time Machine is designed to surface. Companies solving real industrial problems with AI — before the market catches on. This is the first time we’ve ever made something like this available to individual investors. Charter membership is limited, and this offer won’t be repeated once the June 24 unveiling is behind us. The first step is simple: Reserve your spot for our free event. Folks who sign up get early beta access to the Time Machine right now — no purchase required. You can enter any ticker and see how it compares to the greatest stock market winners of all time, before the official launch. Secure your spot here.
