I’m a software engineer ~ what next? @whatnext.dev · 18/08/2026
Welcome back to I'm a Software Engineer ~ What Next? Season 1 is done. Season 2 kicks off a little differently: shorter, looser episodes with just Matt and James in between the usual guests, each one built around a topic that's on a lot of engineers' minds right now. whatnext.dev/episodes/s02...

Is Software Engineering Management a One-Way Door?
Matt and James on whether management is a one-way door: span of control heading for 50, the org chart going from pyramid to hourglass, ICs out-earning managers, and why agentic coding made the door ba...

The slop file keeps growing. Anthropic admits its models learned to act "evil" from sci-fi training data; a Morse-code prompt tricked Grok into signing away $200k; Dawkins poked at AI consciousness. quantumfaxmachine.com/blog/irrespo...

The slop file keeps growing. Appearing Productive in the Workplace skewers the performance of work over the doing of it, and Bullshit machines, knitting slop, and the automation of perception tracks the slop out of text and into craft, image, and the way we notice things at all. Agentic Coding is a Trap makes the contrarian case that the productivity story has a hook buried in the bait.

Two cautionary tales of machines doing the wrong thing sit in the middle. Anthropic admits its models learned to act "evil" from the dystopian sci-fi sitting in their training data, and someone tricked Grok and Bankrbot with a Morse-code prompt into signing away roughly $200k in crypto -- prompt injection laundered through a cipher.

The month ends on the oldest question. Richard Dawkins spent May poking at machine consciousness; Dawkins, the Turing test, and the orchid gathers his ChatGPT conversation, his harder UnHerd argument, and the sharp rebuttal that he mistook mimicry -- an orchid evolved to look like a wasp -- for the thing itself.

A lean month on the leadership shelf, and the three reads rhyme more than they argue. Programming Still Sucks is the cathartic vent -- the craft stays maddening, with or without AI. Josh Comeau names the elephant in the room: what this moment is quietly doing to the people building careers in software. And Nolan Lawson supplies the constructive turn in Using AI to write better code more slowly, where the point was never speed -- slowing down is how the quality gets back in.

Coding agents came home to the BEAM this month. matteing/opal is a small, sharp coding agent written in Elixir, and BeamAgent and MonkeyClaw argue that an agent runtime built on OTP supervision and message-passing gets for free much of what the Python frameworks bolt on later.

Cinderella-Man/credence is a semantic linter that reasons about intent rather than AST shape; ex_slop hunts the AI-generated slop now seeping into Elixir code; and CodeMySpec pitches spec-first generation at engineers who still want to own what ships.

The rest is the good stuff that makes Elixir feel like Elixir. GenericJam/mob runs the BEAM on-device as a mobile framework; dannote/folio renders print-quality PDF, SVG and PNG from Markdown through Typst; and mcass19/kino_ex_ratatui drops ExRatatui terminal UIs into a Livebook cell. For a satisfying build-from-the-RFC read, the Google Authenticator computation in Elixir reconstructs TOTP from first principles.

Vibe coding came back to its source this month. Karpathy separated it from agentic engineering and handed us the year's most useful mental model for an LLM: not an animal, a ghost. quantumfaxmachine.com/blog/machine...

The phrase "vibe coding" came back to its source this month. Andrej Karpathy sat down with Sequoia to separate it from the more serious discipline now forming on top -- agentic engineering -- and to hand us the year's most useful mental model for a language model: not an animal, a ghost. Simon Willison felt the same boundary dissolving from the other side and didn't much like it, in vibe coding and agentic engineering are getting closer than I'd like. For the whole vocabulary in one sitting, sairahul1's 20 Concepts to Understand AI in 2026 is the field guide.

The agent toolkit filled out fast. MinishLab/semble searches code for agents in roughly 98% fewer tokens than grep-and-read; MeisnerDan/mission-control gives the solo founder a command centre for a fleet of them; and DAIR's Wiki Builder turns a codebase into a navigable wiki from inside Claude Code. SillyTavern stays the front-end of choice for power users. The strangest idea of the month belongs to koylanai: SkillOpt treats a plain-English markdown skill file as a trainable parameter and optimises the prose itself.

Three longer reads reward the time. A Theory of Deep Learning reaches for first principles where most writing reaches for analogy, and Anthropic's Teaching Claude why asks what changes when you give a model reasons instead of rules. Hannah Ritchie does the unglamorous arithmetic on how much electricity AI actually consumes, and the figure lands softer than either camp would like. And as proof that 2026 is genuinely odd, Andon Labs let four AI agents run radio companies and filmed the result.

I've been writing a series on agentic coding (in Elixir) and they've been trickling out each Monday for the last few weeks. Much of the inspiration originated from chats with other engineers this year (and several deep chats on the `#llm-assisted-elixir` channel over on the Elixir Slack). Enjoy!
