(Disclaimer: I don't speak for SingInst, nor am I presently affiliated with them.)

But recall that the old name was "Singularity Institute for Artificial Intelligence," chosen before the inherent dangers of AI were understood. The unambiguous for is no longer appropriate, and "Singularity Institute about Artificial Intelligence" might seem awkward.

I seem to remember someone saying back in 2008 that the organization should rebrand as the "Singularity Institute For or Against Artificial Intelligence Depending on Which Seems to Be a Better Idea Upon Due Consideration," but obviously that was only a joke.
