This guy is pretty genius.
Posthumans probably won’t have much more capacity for evil than we have, or are likely to have shortly. So, at least in terms of how many persons can be killed, posthumans will not outstrip us in this capacity. This is not to say that there are no new worries with the creation of posthumans, but the greatest evil, the destruction of civilization, is something which we now, or will soon, have. In other words, the most significant aspect that we should focus on with contemplating the creation of posthumans is their upside. They are not likely to distinguish themselves in their capacity for evil, since we have already pretty much hit the wall on that, but for their capacity for good.
I've had similar thoughts.
