I'm excited to share the early access release of my upcoming book, Regenerative Software, which will be released in full early next year by O'Reilly, one of my all time favorite tech publishers! As a self-taught developer, I learned a lot of what was foundational to my career from early O'Reilly books on UNIX, Perl, sed, awk, etc. Thrilled to finally have one of these animal covers with my name on it.

Multiplayer AI needs to move past the group chat phase. Chats are chaotic, everyone sees everything (creating social & management issues), and they're bad for long projects. Worse, they keep AI trapped inside existing teams, when its real promise is working & helping across them.

Personal agents finding and negotiating opportunities on your behalf with other people's personal agents is the future. And Index Network is building that.
Try out. It feels new and weird and cool. And it's showing the outlines of what will become the predominant way that economic activity and human coordination happens in the wild, wild future that is racing towards us at ever accelerating speed.
Today we’re launching @indexnetwork_
It’s been exciting to watch already. The first 100 people in are hiring founding engineers, raising seed rounds, writing speculative fiction. One said accepting an intro “feels like the early magic of the internet.”
Try it for yourself: index.network/l/088436b1-baf…
The premise: With Index, personal agents can coordinate with each other and thus introduce the right people to their users. They do this by negotiating on their principals’ mutual intents, replacing the need for us to broadcast on platforms and scroll endless feeds.
In practice: You log what you're looking for (“signals”) by talking to your agent, it negotiates on fit with the others, and comes back to you with proposed intros for you to accept or pass on. It learns from each turn to surface more relevant people for you.
As founders, but also just as internet nerds - we feel the expectation to be constantly visible. It can be empowering but also tiring, especially when there’s little certainty in how algorithms will route the right people to see your post. On the market level, economists call this search friction: the idea that many deals are never made because it costs too much to find each other. We call it the right person, wrong time.
So that’s why we’re building Index - we’re keen to see what happens when we take social discovery out of the feeds. It’s possible now because of agents. They can help carry the burden of searching, shouting, negotiating, and coordinating in service of finding your others - and we’re so excited to see how this works in the wild.
We’re building this for a world where you can trust that the right person is not out there, but right around the corner. In fact, we even made a short film about it.
I'm heading to San Francisco next week. My hope is the entire population of the bay area joins this before then so I can have the best serendipitous meetings possible.
Thank you for your attention to this matter.

Excited for this one!
Heading to SF next week to host a dinner discussion with @boxd_sh & some of our smartest friends on the future of software development, deployment, and management.
It's by invitation but we have a couple of spots open for people passionate and building in this space!

Say @hyperseref is "visiting SF for a month and looking to meet other builders who share my flavor of weird."
Enter: his agent sussing out who's around and right for it... and a stacked coffee lineup with the Theos, Priyas, and Lenas stoked to meet him too.

Excited to welcome @chadfowler to AI DevCon NYC! How do we preserve trust and coherence when software is continually regenerated? We’re looking forward to exploring Phoenix Architecture with Chad in Brooklyn!

Our own @chadfowler is speaking at AI DevCon NYC this November. His session will introduce Phoenix Architecture as a way to reason about durability, trust and coherence when AI shifts software from long-term maintenance toward regeneration.
AI DevCon NYC brings together 700+ senior developers and technical leaders in Brooklyn from November 2–4. Use Chad's code CHADF30 for 30% off:

boxd is heading to SF, and a few final spots have opened up for our private dinners:
Dinner 1 (21 Oct, with BlueYard ): an exclusive dinner at a Mediterranean restaurant on the waterfront.
Dinner 2 (29 Oct, with OVNI Capital): a private chef at our home in Potrero Hill.
Expect a great evening and a small table. Know someone we should meet while we're in SF? Please reach out. Event links in the comments below.

This AI season brings you a once-in-a-lifetime opportunity. Regenerative software. The limits and architecture are where software engineers live. Thank you, @chadfowler for pouring your hard-earned wisdom and soul into it.
