It doesn't take a billionaire to do it at this point. In case you've forgotten, there are still plenty of very intelligent humans around. All it takes is one intelligent misanthrope with sufficient access to the resources (not even that expensive relatively, likely not more than $1 million in tools, but i would guess far less is possible), to pull off an attack like that.

I guess billionaires are more malignant/misanthropic/sociopathic/narcissistic than most, and so I could see them being a higher risk factor.

I was kind of joking with you before, but tbh we actually are closer aligned on this than I expected. Including how strange the "effective altruists" are. I was expecting you to be talking about a much more far fetched scenario based on the language in the parent comment.
