I stumbled across EY's writings back before the start of Overcoming Bias, which eventually got me interested in transhumanism, the idea of an intelligence explosion, the Friendliness design problem - oh yes, and also rationality. I concluded back then that how we deal with upcoming supertechnologies (MNT, SI, possibly emulation) will be the deciding factor in what happens to our civilization (or the parts that aren't in simulations with close termination conditions, in any case), and that hasn't changed.
