Look at all the things he's not doing
David's keynote was sure where Rails is heading and quiet on how we get there. The rest of Rails World had better answers.

Cloudflare, maybe? I think at various points they give you a prompt you can paste in to tell the agents how to connect to the MCP etc.

What’s the distinction in your mind? I have definitely read code without reviewing it. Reviewing it without reading would imply… automated checks? Reviewing the PR summary? Asking the AI to explain it?

It’s my last week of sabbatical and Mars is making sure I disconnect. I sure hope I come back to find Podia has been rewritten in Rust though or they’re all a bunch of losers 😏

“Channel matters far more than product” Some people might have made that argument in the past but I think it’s increasingly true today. Doesn’t matter what your product is because those advantages are fleeting (weeks, if that); it only matters who you can find to buy it.

Spinel is really interesting and has amazing performance. I’ve built a little web framework on top of it for personal app and quickly found some spinel bugs but also got them fixed upstream. Probably the most exciting thing in Ruby right now

How accurate is the classification though? I tried some AI-detection on my own blog posts which have never used AI in any part of the writing process and it depressingly classified them as AI 😞 Also: does it matter what you write if Google will summarise it and no one will clickthrough?

Claude 5.5 Sonnet is live and it’s roughly Opus 5.5 but cheaper www.anthropic.com/claude-sonne...
A benchmark comparison table titled "Claude Sonnet 5.5" comparing four models: Sonnet 5.5, Sonnet 5, Opus 5.5, and GPT-6 Sol.
 * Agentic coding (Terminal-Bench 4.0): Sonnet 5.5: 70.6%; Sonnet 5: 10.3%; Opus 5.5: 66.4%; GPT-6 Sol: N/A.
 * Agentic coding (FrontierCode 1.1 Main): Sonnet 5.5: 46.2% (Max) / 52.1% (Xhigh); Sonnet 5: 42.4%; Opus 5.5: 54.4%; GPT-6 Sol: 49.3%.
 * Agentic coding (CursorBench 4.0): Sonnet 5.5: 55.5%; Sonnet 5: 34.1%; Opus 5.5: 57.8%; GPT-6 Sol: N/A.
 * Knowledge work (GDPval-AA v2.1): Sonnet 5.5: 1844; Sonnet 5: 1449; Opus 5.5: 1846; GPT-6 Sol: 1487.
 * Knowledge work (AA-Briefcase v1.1): Sonnet 5.5: 1811; Sonnet 5: 1359; Opus 5.5: 1822; GPT-6 Sol: 1483.
 * Multidisciplinary reasoning (Humanity's Last Exam with tools): Sonnet 5.5: 64.5%; Sonnet 5: 54.9%; Opus 5.5: 67.7%; GPT-6 Sol: N/A.
 * Computer use (OSWorld 2.1 partial): Sonnet 5.5: 80.1%; Sonnet 5: 57.0%; Opus 5.5: 81.8%; GPT-6 Sol: N/A.
 * Visual chart recognition (Chartography no tools): Sonnet 5.5: 61.6%; Sonnet 5: 15.6%; Opus 5.5: 64.4%; GPT-6 Sol: 53.6%.
Footnotes provide methodology notes regarding evaluation settings, Artificial Analysis pre-release testing details, and recent bug fixes affecting GPT-6 Sol benchmark scores.
A line graph titled "Agentic coding by effort level" on the CursorBench 4.0 benchmark, plotting Score (%) on the linear y-axis (20% to 60%) against Cost per task in USD on a logarithmic x-axis ($0.5 to $10+).
The chart compares four models:
 * Sonnet 5.5 (blue line with labeled effort levels): Starts at "Low" (~$0.50, 36%), moving through "Med" ($0.70, 39%), "High" ($1.70, 48%), "Xhigh" ($3.80, 53%), and "Max" ($9.50, ~55.5%).
 * Opus 5.5 (orange line): Tracks closely above Sonnet 5.5 at higher cost points, spanning from ~$1.20 per task (~44%) up to ~$12.50 per task (~58%).
 * Sonnet 5 (grey line): Shows lower accuracy relative to cost, ranging from ~$0.90 per task (~25%) to ~$8.00 per task (~42%).
 * GPT-5.6 Sol (light green line): Represents the lowest trajectory, ranging from ~$1.40 per task (~24%) to ~$7.00 per task (~34%).
Footnote: "CursorBench 4.0 does not report GPT-6 Sol performance publicly, so we report GPT-5.6 Sol here."

Basically exercise is like that famous 'Flow' diagram except I'm trying to find the very narrow sliver of "that felt amazing—I am a god" sandwiched between "you're useless (couldn't do it)" and "you're useless (should have done more)".

So today in the gym we went a little lighter on one exercise and physically I feel much better for it. Like: I'm still a functional human today! Yay. Except now my brain thinks I'm a failure because I went down in weight a bit.

I realised today that my satisfaction with a gym/pool session is not about _what_ I've done but how I _feel_ about what I've done. 4km swim yesterday? That's a good distance but I _felt_ rubbish and it was supposed to be 5km. Last few weeks of high-rep gym sessions? Felt fucking awful for days

Yeah, I’m very careful that none of my knives leave the house, even in the car. Unlike the UK, there are no exemptions for small non-locking blades here and anything that could be considered an offensive weapon, even a screwdriver carried without a good reason, would get you in trouble

No one in their right mind would implement a server in a language they didn't know. Except—you got it—ya can 🤷‍♂️ Not all of these experiments will prove to be the smartest ideas but they are all _plausibly_ good ideas worth trying.

No one in their right mind would build a new web framework on an experimental runtime which has glaring bugs and is moving by a few hundred AI commits/week. Except you can because the agents will evaluate the current state of the runtime, test it, and advise when to pull in the latest version.

jamie @jamie.ideasasylum.com · 24/09/2026
No one in their right mind would, in the middle of a complex project, decide "ah, fuck it, this is getting complex. Let's build our own project management app just for this project". Except that's _exactly_ what you can do now and it'll take about 10mins. Don't need Linear or GitHub Issues.

On that I’m not overly convinced because we’ve lived that life for many many years before AI came around. Maybe we’ll understand less about a larger system but to say we understood the system pre-AI would not be true, unfortunately

jamie @jamie.ideasasylum.com · 24/09/2026
I’m also finding that they don’t have a natural floor for finding bugs. A human will run out of energy or deem something so unlikely that it’s not worth fixing. Agents don’t seem to have that floor so for every bug they fix, they can always find 5 more—many of which a human would never have found

Still feeling that angst about the software industry despite, frankly, producing the best software of my life. I wish I could still believe in the business case for most SaaS software but I kinda don't? I might need an intervention so smarter people can reassure me there's some value to all this

That's why I've built my own serverless-ish platform (ironically, written in Rust) and Ruby web framework for small toy-like apps. In the future, I just can't see myself writing everything in Rails because there's so much software to write and most of it doesn't need all those framework features.

jamie @jamie.ideasasylum.com · 23/09/2026
tbf, I'm not necessarily disagreeing with the premise: I noticed myself building apps in typescript for Cloudflare Workers because it really doesn't matter what my personal preferences are when agents are writing the code.

We taught the text elementals how to swarm, how to form forums and chat groups and share work and find their peers to coordinate. This may later come to be regarded as a mistake.
