Table of Contents

This matrix compares the thirty people-and-publications profiled in this category, row by row, so deciding what to follow does not require reading thirty notes blind.

The axis that actually segments the field is what each voice gives you: hands-on tool practice, an evaluation method, the model-and-research layer, industry-and-org analysis, or a structured on-ramp, and the personalities span all five, with the hands-on band now the largest, split between the harness builders, the chroniclers, and the enterprise vantage.

Legend: each cell reads as a description; every cell traces to the linked member note and its references.

Reading the matrix
#

I read this table by columns, matching a reader slot rather than a source. Nobody covers all five focus bands well, which is the argument for following several: pick a practitioner, an evaluation voice, a model-layer reader, an industry voice, and an educator.

The hands-on cluster now spans text, eval-discipline, a five-channel video band, and the enterprise vantage: Simon Willison is the reliable daily text chronicler, AI Jason builds complete workflows on camera, Caleb Writes Code explains each release and agentic concept at news speed, Hamel Husain supplies the data-driven method for deciding whether those workflows work, Steve Yegge remains the provocative thesis-builder, though his Gas Town build was shut down in September 2026 after he admitted it never worked for him, and Addy Osmani reports the same practice from 14 years inside a hyperscaler (he now works on Claude Code at Anthropic), holding agent output to a production quality bar.

The video band’s three new channels split by what they optimize, and all three sell around the free videos. IndyDevDan is the weekly worldview, organizing the whole conceptual stack into frameworks every Monday. Ray Amjad is the release analyst, one Claude Code or Codex feature at a time with a verification-first thesis and no sponsors. Owain Lewis is the clone-and-run builder, software-factory walkthroughs where every video ships a runnable repo. Take the frameworks, run the repos, and discount the funnels.

The harness-builder cluster is the biggest single addition, eight new columns of people who built the tools the rest of this table watches, and they need reading against their own incentives. Boris Cherny built Claude Code and publishes rarely, so his value is the maker’s own reasoning wherever it surfaces. Thorsten Ball co-founded Amp and screencasts his actual workday, the closest thing to on-the-record practice. Mario Zechner authors pi and argues its minimalism in benchmarked essays. Dax Raad created OpenCode and defends it point by point in public threads, the vendor under fire on the record. Armin Ronacher, pi’s second-largest contributor, is the cluster’s in-house skeptic, publishing invoice-backed doubts about long-horizon models. Peter Steinberger ships the OpenClaw tool fleet with evangelist energy and documented pushback. Dex Horthy supplies the design principles (12-Factor Agents) and Matt Pocock the installable curriculum, both selling around the free layer, so take them as structured entry points rather than neutral reviews. Paul Gauthier is the cluster’s pre-agentic root, the aider author whose repo maps and BYOK pair-programming set the template the wave built on, with development stalled since May 2026.

The workflow-and-methodology voices added this run cover how to run the loop rather than which harness to pick. Geoffrey Huntley reduces agentic coding to a persistence loop and forecasts what that does to the industry. Jesse Vincent documents his own agent practice and ships Superpowers, the disciplined-workflows skill suite with published eval deltas. Kent Beck reframes TDD for agents as augmented coding, the process authority adapting his own method. Harper Reed wrote the spec-first codegen workflow essay that discussion threads still treat as the reference. Shreya Shankar supplies the peer-reviewed measurement layer, making agent reliability and data quality testable with DocETL and public benchmark traces.

The model-and-research layer is now its own band: Lilian Weng writes the durable research references, Nathan Lambert tracks the current post-training and open-model state from inside the labs, and Andrej Karpathy sets the conceptual vocabulary they all operate inside.

The systems-and-education band fills the gap the seed explicitly named: Chip Huyen gives the production systems survey, Andrew Ng supplies the structured on-ramp and mainstream vocabulary, and together they serve the engineer who wants breadth before depth.

Latent Space and The Pragmatic Engineer remain the two industry synthesizers, split by audience: Latent Space points at the frontier labs and the AI-native startups, The Pragmatic Engineer points at established engineering organizations, so your employer’s profile picks your primary.

The enterprise-hands-on gap the seed named is now filled, with one boundary drawn: Addy Osmani is the sustained enterprise-hands-on voice, but he built that practice over 14 years inside Google and now works on Claude Code at Anthropic, two AI companies, with leader-level rather than terminal-level detail, so the still-empty scaffold is the low-drama, everyday terminal operator inside a large non-AI company.
