I said "courage of people wo have no fear of dying" you said "courage in choosing death", very different.
You have not defined what type of "progress" you refer to, but let me just quote one sentence from one random article on that topic [1] "The relationship between population growth and economic growth is controversial." Care to provide a reference for your "This is pretty much a fact"?
> It would be a choice - live forever or have kids.
Wouldn't this mean that within few generations there would be no more kids, as sooner or later each genealogical line will end with an individual who decides to live forever?
> The slow deaths of billions of people, entire generations, is not an acceptable cost for faster progress.
Acceptable by whom? I understand it is not acceptable to you, and I value your perspective, but why do you write it as if it was some form of consensus.
