Highlights from my conversation about agentic engineering on Lenny’s Podcast by Simon Willison
People talk about how important it is not to interrupt your coders. Your coders need to have solid two to four hour blocks of uninterrupted work so they can spin up their mental model and churn out the code. That's changed completely. My programming work, I need two minutes every now and then to prompt my agent about what to do next. And then I can do the other stuff and I can go back. I'm much more interruptible than I used to be.
Kind of goes against the whole deep work principle. Times sure are changing.
2025: The year in LLMs by Simon Willison
My tools.simonwillison.net collection of HTML+JavaScript tools was mostly built this way: I would have an idea for a small project, prompt Claude Artifacts or ChatGPT or (more recently) Claude Code via their respective iPhone apps, then either copy the result and paste it into GitHub's web editor or wait for a PR to be created that I could then review and merge in Mobile Safari.
I have been doing this a lot this past year as well. Most of the site was done this way. First using cursor, then Codex and finally using Claude.
