Written companions to every Tech Dad video — tutorials, explainers, reviews, podcasts.

Every infrastructure bet has an underperformance phase. The bet is not whether the technology is real. The bet is whether you survive it.

Universality is a byproduct of constraint. A counter-example to vibe-coding, hiding inside every phone, browser, plane, and AI agent on Earth.

Workday cut 8.5%. Atlassian laid off 1,600. Klarna said AI could replace 700 agents. The layoff headlines are real — but they're reading the wrong signal. The three engines that protected legacy SaaS for thirty years just broke. YC mapped what comes next.

Tom Blomfield told founders to build 'Garry's G-Brain, but for every business in the world.' We opened the repo, read the code, ran the benchmarks, and found four architectural bets that rewrite how agents should handle memory, routing, and self-maintenance.

The internet is running out of human-written data. Every frontier lab's answer is the same: train models on data the models generate. It's the most consequential bet in AI — and the conditions that made it work on a Go board are, at best, partial for language.

Legendary AI researcher Andrej Karpathy dives deep into the paradigm shift from traditional programming to 'Software 3.0,' where LLMs act as the primary interpreter. Learn the difference between 'vibe coding' and 'agentic engineering.'
