DHH used his Rails World keynote to all but declare the end of human coding, revealing that Hey has been rewritten in Rust, a language he still dislikes. Elsewhere, a rebuttal to the claim that agents make human code review obsolete, Jeff Atwood on the community that LLMs can't replace, and why the Pi team changed their minds about MCP.

Linear reworked their CI pipeline to keep pace with AI-accelerated code output, while the open source Strands harness makes its case on lower token cost. Meanwhile Claude Opus 5.5 arrives amid a crowded week of model releases, with early reports pointing to a leaner, more focused engineer rather than just a benchmark win.

As AI takes over more of the coding, this issue asks what skills the next generation of engineers will actually need, and how they'll acquire them without the years of hard-won experience we relied on. It also looks at the emotional side of the shift, from one developer's rediscovered love of writing code by hand to what still separates good writing, human or AI-assisted, from the kind readers can spot in an instant.

Dan Luu's benchmark of 26 agent testing techniques finds that naming a sophisticated method rarely improves correctness, while Spotify's Portal shows lightweight, hook-routed agents can cut Claude Code token usage by 90%. Elsewhere, Shopify explains why it's abandoning React Native for an AI-accelerated return to native development.

This issue is a single-feature deep dive into The Rise of Open Weights, tracing how the AI ecosystem moved from open research ideals to increasingly closed commercial control. It charts key turning points in cost, capability, and policy to ask whether organisations should keep renting AI access, or start owning the capability themselves.

Open weights models are now matching frontier closed systems, while this week's so-called rogue AI incident was really a containment and access-control failure. Alongside calls to ban Chinese open models, the bigger story is how policy decisions are reshaping who can build, defend, and compete with AI.

Cost and efficiency dominate this week's model releases, with GPT 5.6, Meta Spark and Kimi K3 all positioning performance-per-dollar as the key metric. Meanwhile open weights models close the gap on the frontier, and a case is made for why writing code still matters.
