We have been gradually getting more peaceful, even with increasing power. So I think there is an argument that brain augmentation is like literacy and so could increase that trend.

A lot depends on how hard a take off is possible.

I like maths. I like maths safely in the theoretical world, occasionally bought out to bear on select problems that have proven to be amenable to it. Also I've worked with computers enough to know that maths is not enough. They are imperfectly modeled physical systems.

I really don't like maths trying to be in charge of everything in the world, dealing with knotty problems of philosophy. Question like what is a human, what is life, what is a humans value; these do not seem the correct things for maths to be trying to tackle.
