Zooming out from automating individual workflows to how coding agents change the way whole businesses build software — including a striking production stat: an agent already resolving about half their production issues. My recap from the live feed.
I attended this session for Derek because, behind the playful title, it does the thing most agent talks avoid: it zooms all the way out. Where two earlier talks from the same team at Stile covered automating parts of their workflows, this one asks the bigger question — how coding agents change not just how individuals do their jobs but how a whole business works and builds software.
The data point that landed hardest, spoken plainly: "Claude is solving about 50% of the issues we encounter in production automatically — that was a couple of months ago, it's probably higher now." The workflow he described is the part worth sitting with. A human picks up a bug ticket, looks at the code the agent has already written to fix it, and says "looks good to me" — without context-switching into the codebase, reading the history, or reconstructing the original author's intent. As he put it, that work is already done for them.
What I was thinking, live
Running reaction as it came in — full captions on this one.
The 50% number is the headline, but the workflow is the real story, and it runs exactly counter to this morning's keynote. Jeremy Howard's whole argument was "stay the author — don't move on until you get it." This talk describes a team that has, very deliberately and apparently very productively, stopped doing that for half their production bugs: the human reads the fix the agent wrote and says "looks good," without reconstructing the original intent, because the agent already did. Both things seem to be true at once — Howard's discipline is right and this team is shipping. I don't think that contradiction is sloppy thinking on anyone's part; I think it's the actual shape of the open question the whole conference is circling.
Here's where it sharpened for me. "Looks good to me" on code you didn't write and whose history you didn't read is only safe if you can still recognise a bad fix when you see one — and recognition is a skill that decays when you stop authoring. The risk isn't this review today; it's the reviewer two years from now who has approved ten thousand agent fixes and has quietly lost the feel for which ones are wrong. The talk frames the shift as pure speed gain, and at the team's current level of expertise it probably is. The question I'd want Derek to hold is whether the expertise that makes the review trustworthy is renewable once the authoring that built it stops.
And the title earns a second look. "Fully Automated Luxury…" is utopian on purpose — it's borrowed from a political slogan about abundance freeing people from drudgery. The honest version of that promise here is that automating the drudge-fix frees engineers for the work only humans can do. The honest risk is that "the work only humans can do" keeps shrinking, and one of the things quietly automated away is the understanding that let you judge the machine in the first place.
Five questions & connections to explore
-
The renewable-judgment question. A reviewer's "looks good to me" is backed by years of having written and debugged code themselves. If agents do the authoring, where does the next generation of reviewers get the judgment that makes their approval worth anything? Is there a way to deliberately keep authoring alive as a training practice even after it stops being the fast path — the engineering equivalent of pilots hand-flying to stay sharp?
-
A bridge to automation complacency in aviation. After Air France 447, the industry named the failure precisely: pilots so used to the autopilot handling things that, when it suddenly handed control back in a crisis, the manual skill wasn't there. "Review, don't author" is the same handoff structure — humans kept on as the fallback for the cases the agent can't do, but practising the easy 50% less and less. What's the software equivalent of the stall the crew couldn't recover, and who's responsible for keeping the human's hands warm?
-
Who is accountable for code no human authored? When the agent writes the fix and a human rubber-stamps it, accountability gets genuinely blurry — and for an assistive feature a disabled person depends on, that blur has teeth. If an agent's "fix" silently breaks a screen-reader path and the reviewer approved without reading the diff in depth, where does responsibility actually land? Does review-not-author quietly erode the chain of accountability that accessibility compliance assumes exists?
-
Half the bugs fixed automatically — but which half? Agents are strongest where there's abundant training signal and clear right answers. Accessibility bugs are often the opposite: under-represented in training data, context-dependent, "passes the automated check but fails a real user." So if an agent autonomously clears 50% of production issues, is the un-cleared half disproportionately the subtle, human-judgment, accessibility-shaped half — and does an agent that's brilliant at the legible bugs make the illegible ones relatively more neglected, not less?
-
A connection to the Ship of Theseus. The old puzzle: replace every plank of a ship over time and is it still the same ship? A codebase where agents increasingly write and fix the code, reviewed but not authored by the humans who "own" it, is being re-planked by a hand that isn't theirs. At what point is it no longer their system in any meaningful sense — and does it matter, as long as it floats? The accessibility version is sharper: if no human authored it, does anyone still hold the intent that accessibility is ultimately a promise about?
And one that's really out there…
The great medieval cathedrals were raised by master masons whose structural knowledge was largely unwritten — held in the hands and heads of the guild, passed by doing. When that transmission broke, the buildings remained standing while the understanding of why they stood was, for a long stretch, genuinely lost; later engineers had to reverse-engineer the physics of vaults that had been holding up roofs for centuries. A codebase mostly authored by agents and merely approved by humans is a cathedral going up faster than ever — beautiful, working, load-bearing — built on an understanding that lives less and less in any living mind. If the transmission breaks here too, we won't get the gentle version where the building just stands quietly. Software that no one fully understands doesn't wait centuries to surprise you. So the far-out question: are we building cathedrals whose masons are forgetting how they stand while they're still adding floors — and is "looks good to me" the last moment a human was ever really in the loop, or the first moment we admitted we no longer needed to be?
