Claude Code sub-agents are now fully integrated in our day-to-day workflow.

I think two reasons it's going great for us:

1. The main agent loop plans and then autonomously calls them up depending on the current context. The convenience to not having to remember to do this manually is crucial.
2. As an XP shop, we always had a few very clearly defined roles, like "Red/Green Test Writer", "Code Refactorer" and "Test Coverage Analyzer" and "Code Quality Reviewer" - which were easy to model as sub-agents and describe when to call them up.

Today Thinking Machines Lab is launching our research blog, Connectionism. Our first blog post is “Defeating Nondeterminism in LLM Inference”

We believe that science is better when shared. Connectionism will cover topics as varied as our research is: from kernel numerics to prompt engineering. Here we share what we are working on and connect with the research community frequently and openly.

The name Connectionism is a throwback to an earlier era of AI; it was the name of the subfield in the 1980s that studied neural networks and their similarity to biological brains.

Hah! Even before reading this, I had to think of Heinz von Foerster's talk "2 x 2 = grün" (2 x 2 = green) in which he describes deterministic vs. non-deterministic automata.

His work in second-order cybernetics and later, "the area of self-organizing systems, bionics, and bio-inspired computing; that is, analyzing, formalizing, and implementing biological processes using computers" at BCL feel primordial-soupy to Connectivism.

tldr; @lovable helped her build an app. It helped me find compassion.

This week, my wife built her first app using Lovable. She finally felt what it’s like to get lost in the bliss of creating digital products, and I finally felt what it’s like to be outside of a loved one’s creative process.

For context:

My wife is an executive leadership coach. Her work is in-person, relationship-focused, and non-technical.

I’m a software engineer with 25 years of experience, and for me, making new things has always meant quality time with myself and learning.

But… The love for making things also put pressure on our relationship:

When I got absorbed in coding personal projects, I would vanish for hours, often days, hyper-focused, even thinking about the problem when off-screen.

So, even though I was physically “there,” my wife experienced absence.

She couldn’t understand why I poured so much energy into these side projects. And then my attempts to show her “the latest version” usually made things worse for her: too excited, too technical, too too hard to follow. And then, of course, I would feel misunderstood and alienated in turn. Yeah.

This week, something shifted. For the first time, my wife built her own app—with Lovable. She got hooked. She disappeared for hours, making, testing, playing around, chasing down bugs, refining features, obsessing over details.

Two days ago she sent me this:

“[…] since yesterday, the automatic cataloging of the photos and the recommendation engine have already been fundamentally improved, but right now the database integration is a bit buggy.”

I couldn’t believe it. She had stepped into my world of making. And I had stepped into her world of waiting, standing outside, feeling the distance, rooting for her and at the same time wondering when she’d come back.

That role reversal gave us what years of explaining never could: perspective and empathy.

She now knows what it feels like to lose yourself in digital creation. I now know what it feels like to be left “outside” of it.

Yesterday and today we’ve reflected on this change in perspectives. I feel much more understood in my love for making and I feel a deeper understanding for how my deep-dives felt for her.

Thank you Lovable!

PS: One a side-note, I’m also in awe. In just three days, she fully iterated on her idea and built a solid product with actual non-trivial technology. I say this as someone who’s been doing this for 25 years: her app is getting really, really good.

@lovable PPS: Bumping in hope to hear if others have had similar issues or experiences regarding pre- and post-AI vibe-coding deep dives. @lovable has this come up at all on your radar?

i never took the dead internet theory that seriously but it seems like there are really a lot of LLM-run twitter accounts now

My personal analogy: The Internet today is now what TV became in 1999. And AI today is now what the Internet became in 1999. TV didn't go away but it was clearly and instantly relegated to second choice. The Internet felt more trustworthy and real. I wish I could put this more succinctly but, alas.
