I'm not talking about hacking, it's not an existential threat, it's a consequence of sloppy software and business practices, hacking attack actually help by forcing better software and bankrupting the incompetent businesses - there are currently too many of them due to political reasons, if we're lucky we'll see political improvements as well.
> like the Binance hack
Binance and crypto in general is a larger threat than the sum of all AI, it's legalized corruption, the question is why we are worried about AI but not about crypto.
Your other points refer mostly to state actors but as I said before, those risks are independent of AI and they have existed long before models were a thing. I suspect you, as many others, lacked information about the WMD situation in the world and became aware of it only in the context of AI, but if you remove AI you'll see that very little changes.
About biological weapons in particular, they're easy, they already exist and have been studied for years, AI can contribute very little to the downside here but it can help us tremendously with detecting and protecting from them.
The real problem with bioweapons is sloppy regulations and totally dysfunctional international treaties. The problem isn't AI, it's the lack of rational policies, I wish politicians were as serious about WMD risks as you are about AI, but that's not the case today. AI fearmongering is just a political tool used for the benefit of certain special interests.
