When 2 people vote "yes" on the same AI governance rule, leave the room, and fight for 2 years over implementation, it's because nobody agreed on the physics of what they were building. Stop fighting over labels. Debate the choices www.jsnover.com/blog/2026/07...

“Risk” vs. “Risk” vs. “Risk”: Why AI Arguments Fail Before They Even Start
Inigo Montoya once said, “You keep using that word. I do not think it means what you think it means.” Ask members of the AI Triad if they want to reduce “risk.” They will al…

It highlights the point - AI as-is is unreliable.

LLM models are engines of bullshit. Your system does not have to be. That's a choice, and it's yours. Skip the engineering and you're shipping a bullshit system. Do the engineering and you're not. www.jsnover.com/blog/2026/07...

Super excited to share my work tomorrow with my fellow fellows & circle of friends at the Berkman Klein Center for Internet & Society @ Harvard University. This project has totally consumed me. It feels less like doing a project & more like the project is a force of nature using me to be birthed.

My talk at the PowerShell conference makes the point that developers do not care about Admins. That is why they produce ... things like this. That is why I designed PowerShell so you can clean up their ... work. (even though you shouldn't have to).

It is metaphysically impossible to build a safe general-purpose chatbot. Not difficult. Not expensive. Impossible. A system with an infinite goal space cannot be made safe. That is a structural contradiction. New post: www.jsnover.com/blog/2026/03...

AI safety is a category error. AI is not a system. AI is a component of a system. Systems can be safe or unsafe. Components cannot. New post: www.jsnover.com/blog/2026/03...

I spent 8 years at hashtag#DEC watching the deal get worse. At first I thought it was just the economy. Then I reverse-engineered what was actually happening. It was a deliberate strategy. And I think you're going to see it again. New post: www.jsnover.com/blog/2026/03...

The first 1/2 of my career was a deal. I was a consistent top performer at DEC for 8 years. One bonus: $800. That's what my dad's entire career looked like too. We've been living in very unusual times. SAVE EARLY / SAVE OFTEN.

If you are not occasionally overwhelmed by what is going on with AI, you are either: 1) Not paying attention. 2) Not understanding what you are seeing. 3) Made of much sturdier stuff than I.

A story from early #PowerShell days when my sense of diplomacy was strictly "pre-operational." I asked my new boss—a 20-year Windows veteran with a Physics PhD—if he was an idiot because neither of us could debug a thrashing system using GUI tools. www.jsnover.com/blog/2026/02...
