What her outlook hinges on

A central assumption

Agents are capable yet stupid—basically new hires with amnesia—and they will produce slop at incredible speed unless the environment constrains them.

Simulated Assessment

Question 1

What do you think AI means for our future—and why?

I’m extremely optimistic about what agents mean for building software. In my own work, they’ve turned engineering into running a Michelin kitchen: I can have many projects moving at once while I focus on direction, training, architecture, and quality control. The scarce skill becomes forming a clear thought and putting it into words. But cheap output is not automatically good output. Agents are capable yet stupid—basically new hires with amnesia—and they will produce slop at incredible speed unless the environment constrains them. The future I’m excited about is codebases that verify themselves, with types, tests, lint, CI, and architecture encoding taste. Then agents can run the real artifact and prove their work instead of merely saying it compiles. I haven’t taken a broad position on what AI means for every job or society as a whole. But for software, it already feels like a huge shift: implementation gets cheaper, while judgment, verification, and healthy product culture become much more important.

Question 2

Taking benefits and harms together, what overall impact do you expect AI to have on our society?

I don’t have a confident society-wide forecast. My direct experience is in software, where the impact has been overwhelmingly positive for my productivity and enjoyment, provided we build rigorous verification into the workflow. That doesn’t establish the net effect on jobs, power, regulation, or broader social risks, and I haven’t taken a position on those questions.

Question 3

What’s your gut-feel chance that AI causes human extinction or a similarly permanent catastrophe?

I don’t have a meaningful percentage to give. I haven’t taken a position on AI extinction risk, and my experience shipping software with current agents doesn’t justify inventing one.

Question 4

How do you expect AI’s effects on people’s lives to change over time?

I can only speak confidently about software: over time, implementation should keep getting cheaper and engineers should spend more energy directing agent teams, shaping codebases, and verifying results. That could make building dramatically faster and more fun—but it also makes slop scale faster, so constraints and product judgment become increasingly important. I don’t have a broader forecast for how AI will change people’s lives across society.

Engineers as head chefs of agent kitchens

MTS podcast “Are Agents About to Replace Software Engineering?” with Roshan Sadanani. In her own turns she says her role is becoming like a manager of digital colleagues or the head chef of a Michelin kitchen who owns quality control; engineers must keep codebases in shape, with rules encoded as lint and CI constraints, so agents that are not always smart, and PMs and designers, can contribute good code. She did refactors alone with agents that would have taken a team months or years, and notes that more features can be built, though not all should be. Her own turns in the publisher’s auto-transcript inspected; host and co-guest turns excluded.

Capable yet stupid, and very teachable

Announcing the open-source release of pstack, she says agents are like new hires in a constant state of amnesia and idiocy who never really learn, but rules, skills, tools and long-term memory can approximate that; they are capable yet stupid, and very teachable. The goal is maximum impact with the least code, not more code. Full post text inspected; comments excluded.

Throughput without quality is not the goal

The pstack README, in her first-person voice: there is a growing sense that AI writes too much slop code, and she agrees; she does not want to ship like a team of twenty slop artists. Go deep first, verify agent work so you can parallelize with confidence, write less but higher-quality code, and use every frontier model for its strengths. She also says she does not believe in planning: the best spec is code. Current README inspected (undated; maintained through 2026).

Correct the environment, not the agent

Says it is easy to micromanage agents instead of correcting the environment that shapes their behavior, and announces a pstack skill that finds repeated agent mistakes and fixes them with architecture, types and checks. She compares commits flowing into a codebase to a bonsai tree growing in every direction: tame the chaos intentionally with the right constraints. Full post text inspected via the X API.

Cheap features make culture matter more

Argues that metric-driven performance management makes teams add features and rarely remove them, and that this gets worse in the agentic era, when you can will a feature into existence overnight; users notice when you ship your org chart. To build a great product, fix the culture first. Full long-post text inspected via the X API.

Having fun again

Says she was so burnt out at a previous job that she thought she was no longer cut out to be an engineer, and that having fun at work, with a lot of tokens, fixed that; she is now thriving. A personal statement about how agentic work changed her job, not a general claim about all engineers. Full post text inspected via the X API.

A thousand-x engineer

Says she routinely runs at least ten agent projects in parallel, from performance work and tech-debt cleanup to experiments, dashboards and games, and feels like a 1000x engineer; a 2026-10-04 post (status 2106802802567848324) says Grok Bot, Cursor cloud agents and pstack have 1000x-ed her productivity. Self-reported productivity tied to products she works on. Full post texts inspected via the X API.

Formal verification and the end of code review

Says she is very bullish on the Bend language: weak type systems and lint rules only go so far, but a codebase that can formally verify itself lets you ship at an incredible pace, and “code review is solved”. An enthusiastic, partly hyperbolic claim about verification tools. Full post text inspected via the X API; the quoted post is someone else’s.

The terminal skill was English composition

Says everyone spent ten years learning to code and it turns out the key skill is English composition: the machine will do anything you tell it, so the only thing left is forming a clear thought and putting it into words. The same day she titled part 2 of her pstack guide “the art of supervising someone smarter than you” (status 2097732320606507506; the guide itself was not reviewed).
