Closed Source AI at least can be controlled. See the directive of the US government regarding Fable (even if one disagrees about the directive there is no doubt that it is effective in shutting it off) or the safe guards by a corporate structure (even a profit driven one). It is schizophrenic to praise Anthropic for refusing the Department of War full access to their models but at the same time root for Open Source models.

> In terms of bioweapons, I expect that closed-source AIs will be heavily optimized against helping with these, and open-source AI will be banned after the first warning shot (or become economically prohibitive even before then).
