Surely I can at least try to live up to the example set by men like Turing, Tesla, and Boltzmann, who sacrificed so much to advance human understanding so far.
I expect most of them enjoyed the ride, so describing the process in terms of instrumentally justified personal sacrifice seems inaccurate.
The sad news broke tonight : Neil Armstrong, the first human to ever walk another world, died today. We lost him forever. He died before we could defeat death.
Once again the horror of death strikes. This time, in addition from wiping from us forever a hero of humanity, he wiped from us forever a memory that will never exist again. Never again will a human being be able to experience being the first to walk another world. That beautiful experience is lost forever too, along with all the memories, dreams, desires and wishes that made Neil Armstrong.
But thanks to him, humanity made a giant leap. We'll fill the stars and conquer death. The spark of intelligence and sentience will not extinguish. That's the best we can do to honour him.
