• That it is software means that any given model can be easily ordered nationalised or whatever.
• Everyone quickly copying OpenAI, and specifically DeepSeek more recently, showed that once people know what kind of things actually work, it's not too hard to replicate it.
• We've only got a handful of ideas about how to align* AI with any specific goal or value, and a lot of ways it does go wrong. So even if every model was put into public ownership, it's not going to help, not yet.
That said, if the goal is to give everyone access to an AI that demands 375 W/capita 24/7, means the new servers double the global demand for electricity, with all that entails.
* Last I heard (a while back now so may have changed): if you have two models, there isn't even a way to rank them as more-or-less aligned vs. anything. Despite all the active research in this area, we're all just vibing alignment, corporate interests included.
