I mean, seriously, we all know we can't travel to other stars right now, but at some point we are going to conquer the physics that will allow us to travel long distances in a short period of time. It may be a long time from now, but it is still worth exploring.....
He pretty much summed up his thoughts with the statement of why do we care about the extinction of the human race when we will be long dead and gone anyway. That statement alone shows how this guy thinks....
Ah well, there will always be people who want to do the impossible, or the improbable. It's an interesting read, and seemingly well-reasoned and informed. As progress marches on, people will revisit the subject over and over - there's no danger of the human race giving up on such things in the long-term.
It seems to me that our biggest hurdle will be energy production, and that's the case for a lot of things we'd like to do. We've got to hold out hope we discover something better than what we've got now. Cheap, safe, reliable, renewable energy would be nearly the revolution that agriculture was.
As for conquering the physics that allow us to travel long distances in a short time. . .well, we might instead make a discovery that, once and for all, shows us we cannot do any better than a large portion of the speed of light. We can hope (and I certainly do), but only the discovery itself, and the transformation of the science from theory to practical use, will tell.
The comment about "why do we care about the rest of humanity when we ourselves will be dead" - well, I imagine many people have had that cross their mind in the course of considering this matter. In the final analysis, the human race is our extended family. We can't let it die any more than we could let our own family die, not if we can do anything about it. Beyond that, the human race is our own immortality, in a way. If the human race dies, than certainly any portion of ourselves that might remain alive - any thoughts, any deeds, any shared beliefs - will surely die with it.
