I don't agree Greg, at least in your conclusion. We can easily fall into the mistake of thinking like doomers, and this will be the biggest mistake we ever made, this would be the mistake that the negative powered entity / emergent property associated with us, hopes we carry on making, always at profit, this will be how we might end without ever knowing how different things could have been, if we'd just been a little less concerned with death and how to die, than with life, and how to live. I explained more also in my own response to Mike.
