We have tons of controls around nuclear technology, both weaponized and not, and we have tons of controls around cars, both weaponized and not.

I am asking: what are the controls here, are they sufficient, are they robust to rapidly increasing market incentives, are they robust to increasing technological capability?

So far the answer is that it's hard to control these and it's hard to predict their development and deployment. That is an _increase_ in risk, not a _decrease_.

By analogy:

"Hey we should put seatbelts in cars"

"Don't worry about it, we don't know how to make a seatbelt that does anything useful above 5mph and everyone will soon be in a car that tends to travel at 100mph anyway"

The rational response is not to load all of civilization into the car!
