LLMs are currently the technologist’s Rorschach test, and it’s a lot

LLMs are trivially susceptible to β€œDon’t think of an elephant” behavior. Now all my agent files will only contain `Elephants.`

There's no better form of time travel than listening to the music of your teenager years.

Do companies not need people to build software anymore… or do people not need companies to build software anymore?

Yeah, one day.

Here's what I do now: watch youtu.be/00_hBrQFfzw?... and replace "spice" with "RAM" and "interstellar travel" with "everything".

Technologists reflect: friction is not a universal liability, but rather a tool.

The first edition is one of my top favorite technology books of all timeβ€”cannot wait for this second edition.

I’ll also say that due to how it’s written and the content being high level, the audiobook version is my top favorite technology audiobook.

From building fully hermetic software build and packaging solutions, to implementing consensus protocols for distributed systems, to writing successful developer and operations tooling, I thrive on hard and necessary challenges.

If you have hard and necessary challenges, I think we should talk. 4/4

I've been developing application and systems level software for well over 20 years, primarily in Rust professionally for just over 10 years and working on open source codebases for most of my career, so if you'd like to know how I work, & how I evolve my practice, I am a very open book. 3/4

Nothing is certain in early stage startups & I’m grateful for the opportunity to apply my craft, science, & engineering on some of the hardest technical challenges.

I’m more of a β€œpast informs and influences the future” kind of person so I’m far more excited with what is next. 2/4

It’s official: I’ve wrapped up 6 years working with the best team of my career at System Initiative. I’d like to thank Adam Jacob, Mahir Lupinacci, and Alex Ethier for putting their trust in me and being their first employee hire. 1/4

Me: I need options to solve X
LLM: Great idea! Here's options A, B, C, I prefer B

Me: Hm, none of those are great, are you sure there aren't alternatives?
LLM: Great point! There's a better approach in option D

Me: D is still too strange...
LLM: Right, I have a better solution: E!

Me: ...

Actual response:

"Brilliant insight! Yes, absolutely! Using Result types consistently throughout makes this much cleaner and more type-safe."

I just blew Claude Code's mind.

At least, it's been over 6 minutes since I had an admittedly great idea & it's still "thinking".

I still remain highly skeptical of blanket trust in & applications of LLMs but I'm finding an intentionally configured Claude Code with Skills leads to a powerful brainstorming & planning system.

I haven't felt this generally creative in a long time & it's mostly due to "writing things down".

Last night I had a pretty vivid dream of playing the original Battlefield 1942. I remember when my friend showed me this game for the first time. I've never been so blown away by any video game experience as that day. It felt like anything in the environment could be manipulated and used.

State Files Are a Crime Scene State files stall collaboration and punish refactoring. System Initiative fixes both with real-time simulation and change sets.

State files drift, lock, and lie. Real-time simulation keeps infra accurate, collaborative, and safe to change. That’s @systeminit.com

What Will Surprise You About System Initiative Five surprising things that happen when people first see a System Initiative demo - it's not another DevOps tool at all

Most tools promise faster automation.
@systeminit.com promises something different: a new way to think about infrastructure.

Not just code. Not just pipelines.
A system that models reality, simulates change, and shifts how you approach every decision.

I’m fascinated how the concepts in Promise Theory (for me: autonomous agents & the idea that β€œall you can do is ask another, never command”) apply to complex systems, human interaction, societal cooperation, etc. Thank you, Mark!
