In the face of generative AI coding agents, the role of human-led architecture becomes even more important in the crafting of software-intensive systems.

Frankly, I find relegating hiring to an AI incredibly off-putting. I would never consider working for a company that thinks the hiring decision is so unimportant that it doesn't need to involve humans. It doesn't bode well. 3/4

I am less worried about the cyber attacks from Ai agents and more about the cyber attacks against Ai agents. The first would be an attacker using a model to carry out attacks. LLMs often make this annoyingly hard, they refuse too much. To jailbreak them you need trained criminals which are rare.

A fortnight of headlines about AI killing us all, and the thing actually coming at us is getting little attention as a result. It's not the models getting smarter, it's that we're wiring them up to everything, and nobody has worked out how to do that safely yet. blog.robbowley.net/2026/09/18/t...

In amongst all the AI madness, people seem to have forgotten that the point of working in very small increments with very frequent releases is to get feedback sooner so that we can adjust what we're building to best meet our customers' needs. 1/5

Job applicants are using AI to write resumes and prep interview answers. Companies are using AI to screen those applications and conduct initial interviews. We’ve officially automated both sides of a process meant to measure human connection. The irony is genuinely unreal.

Interesting article, I've seen a few articles recently from experienced XP background type folks saying they're dropping lower level TDD in favour of more outside in acceptance/E2E test driven approach

After 25 years with TDD, we are now parting ways. The incremental TDD steps were great for human cognition, but didn't survive the transition to agentic coding.

for the haters - bad news, i am afraid. literally every Fortune 500 company is using AI to develop their products and services. in many cases they're no longer even doing manual code review. i hate to break it to you, but if you won't use services built using AI you just checked out of modern life.

Why does EventStorming insist on past-tense sticky notes? "Order placed." "Payment confirmed." "Item dispatched." It forces precision. It anchors the room in shared reality instead of assumptions. We broke down the full grammar in our latest blog post: buff.ly/bieandh

One hallmark of a lousy app is that it's chock full of features. A good app does one critical and necessary thing well. A pile of features typically does nothing but add clutter and make the app harder to use. 1/12

If everything is potentially a lie whom could you trust? How can we establish a sense of "truth" (knowing that our body of knowledge is not static and truths are scarce in a complex world)? GenAI brings doubts to the next level but the fields of the epistemic apocalypse were already well fertilized.

I honestly think Domain-Driven Design (DDD) is key with AI, as important as it was before AI, for a few different reasons. The main is that even the best models can't design a good domain model... but they can help you to create a better one.

Agile Software Development is NOT break big projects into small sprints. Agile Software Development IS build something, then iterate. I have seen so many teams spend extraordinary effort on the ceremony of Scrum, and never once manage or even try to put some early idea in the hands of users.

A vicious cycle of four steps surrounding a black cat with a thousand-yard stare and a dapper little tie. The four endlessly cycling steps read:

-going forward we're gonna need more of your data to make sure it's you

-ahaha youre not gonna believe this but we had a bit of a data breach

-your data is probably for sale online now

-that means someone could easily impersonate you

If you are using AI without a way to continuously validate its output, you are flying blind at high speed, and the inevitable crash will be much bigger. Ultimately, AI doesn't replace software engineering; it simply exposes teams that were never really doing engineering. 4/10

One of the dysfunctions that AI amplifies is the software industry's focus on output. The move to AI is all about increasing output. Robot monkeys type faster and produce more output than people. The problem, of course, is that it's never been output that's the problem. 1/10

To me, tests are part of your system and its architecture, not a separate thing that's tacked on as an afterthought. As such, architectural principles that pervade the system must extend to the tests. Testability is an essential architectural characteristic that pervades the system. 1/9
