I think many in the field see intelligence as positive - and think that intelligent machines will reduce automobile accidents and liberate humans from much tedious drudgery.

Since at the moment, things seem to be proceeding at a managable pace, there seems to be little demand for elaborate braking systems.

Also, those who feel the most need for slowing down are probably those least well placed to influence the rate of progress.

Attempts to prevent a "race to the bottom" are likely to prove ineffective - and seem to be largely misguided. There is bound to be such a race - so, we should exert our resources where there's a chance of making a difference.

s anyone actually working on developing a protocol for international regulation of artificial intelligence,

At this stage I would avoid doing that. The more you try to convince those with power that they should make rules against AI the more they are going to think that creating an AI is something they need to do!
