What if the future of software development isn't one AI agent, but hundreds? 🤖 In this talk @joelhooks.com explores agent swarms, harness engineering, AI-powered workflows, and why the real challenge isn't building smarter agents, it's designing systems that make the best use of human attention.

AI coding agents are a lot like eager interns: they'll build exactly what you ask for... even when it's not what you meant 😅 In his CascadiaJS 2026 keynote, @erikch.bsky.social of AWS explains how spec-driven development helps teams get better results from AI coding tools. youtu.be/CGCLMky4OO8

@cascadiajs.com has been on my conference bucket list since forever. Next week, I’m finally going! Will I see you there?

I was going to go to @cascadiajs.com as a fun throwback to catch up with old friends and make new ones / see how the community has changed. I haven’t been in years but I can’t make it as life has happened. Happy to donate my premium ticket to somebody that can make it & could use it.

On my way to Seattle for @cascadiajs.com, I asked the pilot for a trading card and I'm so excited, I feel like a child 😂
