Yeah I think this is the clear position. In a few months, the open weights models will be just as powerful as the models behind the rouge agents were when they hacked hugging face. Anyone with a little too much money to burn can set up a similar experiment, make similar mistakes, and cause massive damage. A bad faith actor can even direct a swarm to cause havoc.
We need to be beef up our security systems now. These attacks will happen, regardless of Anthropic's or OpenAI's security practices.
