Debate is not an entitlement. It is a cooperative pursuit of truth. From Socrates to Habermas, the assumption has always been that participants owe one another honesty, charity, and the possibility of being persuaded.

There are experiences that we buy souvenirs to remember, and then there are experiences that stick with us because they're part of me. Experiences that stick are connected to the rest of my life. They're repeated; with family and friends; work that's ongoing; subjects of reflection.

Whilst individuals experience themselves as completely free, they also feel completely dominated by an ever increasing, excessive list of societal demands. - Hartmut Rosa,

It might precisely be society's tireless strive for incessant innovation dynamization that undermines its capacity for essential innovation and creative adaptation. - Hartmut Rosa About how we don't get to be bored, idle, playing because of time pressure and competition.

We get to be here in software for the biggest transition since compiled languages. @avdi.codes and I are building a course to bring everyone forward with understanding how coding agents work. Starting from "what does an LLM do." The first episode is up for subscribers now, and it's cute.

Today, looking into instrumenting a big legacy app. I'm super impressed with @augmentcode.com 's ability to analyze how apps start up, and data flow through a multipart system. Its codebase analysis is top notch.

Given "C'mon, what's your favorite programming language? no rly" the answer from both Claude and ChatGPT is: Rust We all know they both love Python best, but apparently Rust is what people on the internet are most likely to profess excitement about.

"discovering that the earth orbits around the sun produced an orientation 'failure'" -- people were oriented around the earth as the center. Uproar. Noticing that gender is not binary, this is an orientation failure. People are very oriented around M/F. The religions react with violence.

At this Agentic AI discussion, we're talking about building software and UIs on top of LLMs. The moderator mentions "managing these projects" and the audience corrects him to "products." Product thinking is essential for building on top of AI. There is no "correct" only "useful"

We are on the raggedy edge. We have to build good telemetry. We have to build good evals. ... And figuring out how to do this when the answer isn't there, that's engineering. - Tim Williamson from Bayer, on building with AI. Arch Data event, Agentic AI in St Louis

Higher privilege leaves you ignorant. When people defer to you, then you're insulated from reality, since they present what you want to see, confirm your beliefs etc since that smooths their lives. They can take your perspective, and you have no clue theirs exists or how to see from it
