Your job is being automated. Your company knows. HR has the script ready. I write about what's actually happening before it happens to you. Weekly audit ↓


There are two ways to build AI for mathematics. One is to work in private and surface results after the fact. The other is to put real tools in the hands of mathematicians, learn from real use, engage in public, credit the community you build on, and support the ecosystem itself. We believe in the second model. Mathematics is a profoundly human endeavor. AI should strengthen mathematicians, not route around them. Build with mathematicians, not around them.





JUST IN: AI cow collar startup Halter raises at $2,000,000,000.00 valuation, uses proprietary “cowgorithm” to herd cattle.




The same companies selling you the future are borrowing money to build it.





Evals are the new PRD. The companies building AI products that actually work are running 12.8 eval experiments per day. Here is the playbook with @ankrgyl, Founder and CEO of @braintrust ($800M valuation, behind Vercel, Replit, Ramp, Zapier, Notion, Airtable): ⏱ 1:43 Why vibe checks stop scaling ⏱ 6:35 Evals are the new PRD ⏱ 8:45 The Claude Code evals controversy ⏱ 18:48 Building an eval live from zero ⏱ 29:51 Connecting Linear MCP and iterating ⏱ 39:12 Why you need evals that fail ⏱ 43:36 Offline vs online evals ⏱ 47:40 Three mistakes killing eval culture The core framework: every eval is exactly three things. A set of inputs your product needs to handle. A task that takes those inputs and generates outputs. A scoring function that produces a number between 0 and 1. We built one from scratch on camera. Score went from 0 to 0.75 in under 20 minutes.













@mcuban Love the NBA analogy. I’d push back slightly on tribal knowledge though. Most people aren’t hiding it on purpose. They just never had a reason or a system to document it. This is why a lot of lessons learned in delivery end up recurring. People don’t learn from others’ mistakes.
