I suspect LLM weights will be treated like nuclear material, and there will be a thriving black market in AI models and services when all is said and done. Then our security and intelligence apparatus will align after identifying and shutting down rogue operators, and it will be the responsibility of everyone else to be secure against attack (already is for government entities, not that I disagree but shouldn't excuse borderline criminal behaviour).
But very little accountability for the big end of town. The laws already exist to pursue damages against companies whose systems breach others. They just need to be applied, but I suspect this is going to be the wedge to drive through a bunch of laws that protect big money and punish the little guy. I would like to be wrong.
For them, "Winning AI" is effective winning capitalism, winning militarily, and winning the world.
Nothing like "accountability" is going to be allowed to get much in the way of that.
