Deep Dive

Tuesday morning. Treasury headquarters, Washington DC. The Treasury Secretary and the Fed Chair in the same room. Across from them: the CEOs of Bank of America, Citigroup, Goldman Sachs, Morgan Stanley, and Wells Fargo. Not on anyone's public calendar. The reason was an AI model. Anthropic's Mythos — internally Capybara, a new tier above Opus, priced at $25 input and $125 output per millio...

230 oil tankers anchored in the Persian Gulf with nowhere to go. Oil at $126/bbl. Gas above $4/gal. South Korea's worst trading day in 43 years. The largest disruption to world energy supply since the 1970s — through a 6-mile navigable corridor. Geography is the whole story. Two 2-mile lanes plus a 2-mile separation zone. 135 ships per day. 20 million barrels of oil — 20% of global petroleum c...

$50. That's what it cost to discover and exploit a 17-year-old vulnerability in FreeBSD. Full remote code execution as root. Every scanner in the world missed it. Two weeks before the Claude Mythos system card dropped, the company that built the most powerful cybersecurity AI in history left 3,000 internal documents on a misconfigured CMS. That's the gap this episode is about. Mythos is a...

This is not a fluff piece about smart pet feeders. There is a drug in FDA trials right now that could extend your dog's lifespan. If approved, it would be the first lifespan-extension drug approved in any species. Loyal for Dogs has two drugs. LOY-001 targets IGF-1 in giant breeds — a Great Dane has sky-high IGF-1 and lives 7-10 years, a Chihuahua has low IGF-1 and lives 14-16. Bring a Great D...

System design interviews are partly arbitrary. Interviewing.io analyzed 1,000+ mock interviews. 80% of candidates score inconsistently across them. Same person, different day, different result. Even strong candidates (3-of-4 average) fail 22% of the time. Almost one in four. But the same data says preparation matters more than you think. Because consistency is the edge. The 6-phase framework that...

Four companies. Billions of users. Same underlying problem, completely different answers. And one shared set of building blocks underneath it all. Netflix. 325M subscribers. 1,000+ microservices on AWS. In 2008, a monolithic database corruption took down DVD shipping for 3 days. That triggered a 7-year cloud migration. In 2011 they built Chaos Monkey — software that randomly kills production serve...

Every token from ChatGPT, Claude, or Gemini runs through the same chain: tokenization, embeddings, attention, KV cache, quantization, hardware. Each step is the bottleneck somewhere. Hero stat: GPT-4-equivalent capability fell from $60 per million tokens (Nov 2021 GPT-3) to 7 cents (April 2026). A 300X collapse in under four years. This episode walks the full mechanism, then the economics. Tokeniz...

Gartner: 40% of enterprise apps will include AI agents by end of 2026. And 40% of agent projects will be canceled by 2027. Same number, same organization, same year. This episode pulls apart the architecture under the marketing. A chatbot is a function — input in, output out, one round trip. An agent is a while loop. It keeps calling the model until the task is done. That's the entire distinct...

25% of engineers who pass Amazon's technical bar get rejected on behavioral. At senior level, 63% get downleveled. Not because they can't code — because their stories showed mid-level scope when the role needed senior. Every big tech company runs behavioral. They all test different things. Amazon: 16 Leadership Principles + Bar Raiser veto. Interviewing.io's compression — lead with cus...

AI training on internet text has hit a ceiling. The next frontier is physical reality — data you can only get by running experiments, moving robot arms, flying drones through smoke. Four companies closing that loop. Periodic Labs. $300M seed, pre-revenue. AI scientists paired with robotic chemistry labs. Fully autonomous loop: foundation models hypothesize materials, DFT simulations sanity-check,...
