Transhumanism is happening, and sooner than we might think. Ray Kurzweil's timeline is optimistic, but possible. We have to take it carefully, but frankly, it can only be great for humans. We lose so much time, energy, focus, creativity and compassion through negative emotions such as fear and anger. These emotions were very useful for our ancestor species surviving in the jungles, but they are just unnecessary baggage today.
That's what I think this is truly about - enabling humanity to achieve its true potential.
Awesome Twitter list by the way!
