A vast amount of technological knowledge (e.g. how to create poisons, manufacture bombs) has mass destructive potential if it can be scaled. The difficulty, just like with AI, is scaling, and this mostly self-regulates (with help from the government).

For example, you can build dangerous explosive devices in your garage. That knowledge is widely available (google "Anarchists Handbook"). If you try and build thousands of them (enough to cause mass destruction) the government will notice, and most likely, you aren't going to have enough money and time to do it.

The exact same thing will happen for "dangerous uses of AI". The only actors which have the hardware and capital to cause mass destruction with AI are the big tech firms developing AI. Try running inference at scale on even a 30B parameter model right now. It's extremely difficult unless you have access to multiple server-grade GPUs which are very expensive and hard to get ahold of even if you had the money.
