I do think his views are important but he falls into the most common trap: taking a firm stand on little clear evidence.<br />We haven't even taken enough effort to find if life arose on Mars, surely the first step.<br />Gregory BenfordGregoryhttps://www.blogger.com/profile/09507537950789426671noreply@blogger.comtag:blogger.com,1999:blog-1695280310697378421.post-2404799581065586572009-09-17T09:07:43.876-07:002009-09-17T09:07:43.876-07:00Mike Flynn, your points are well-taken, but I was ...Mike Flynn, your points are well-taken, but I was not, maybe, =entirely= serious with that post (though I do think there's plenty of intelligent life.)<br /><br />I just wanted to use the cliche "waste of space" in a (I hope) creative way.

We've also had 64 years during which we could have put that energy into colonizing the entire Sol system and really reaching to the stars. This would have put us a good ways toward being resistant to the first possibility. Our present reality is between these. <br /> Maybe I'm expressing my optimistic side (didn't know I had one!)when I say I believe these extreme choices are typical of a technological society of any species. <br /> Extrapolation/tangent: I'm not a contemporary of Thomas Jefferson. I'm not likely to be a contemporary of someone born in 2050 CE. That's not to say none of us did/do/will not exist. I can see how this idea can extend to entire societies, whether or not they exterminate themselves. I suspect that in future millenia explorers will find evidence of more deceased societies than currently existing ones. <br /> Makes me want to reread/review "Cosmos". <br /> James, having to be "disaster minded" or not depends also on what's appropriate for the situation. Doing sales, for example, one must look for what CAN go right. Doing engineering one must look for what CAN go wrong so as to design the thing to be safer.Markhttps://www.blogger.com/profile/16962224347551157239noreply@blogger.comtag:blogger.com,1999:blog-1695280310697378421.post-90767285665945647562009-09-08T14:15:10.121-07:002009-09-08T14:15:10.121-07:00I don't know enough about it, I guess, but it ...I don't know enough about it, I guess, but it seems to me that any theory about how common complax life might be is both useless and likely to be wrong.<br /><br />It isn't liek we've found a few hundred worlds that might be inhabited, but aren't.<br /><br />We haven't even scratched the surface of the universe, but we're already talking about "rare earth."<br /><br />What we do know for certain is that planets are very common, and the only earthlike planet we've been able to examine is teeming with life. We have life on this planet even in areas of the ocean where the sun never reaches, and volacic erutions create conditions where life shouldn't be able to exist at all.<br /><br />Let's actually go out there and look around for a bit before we start tarlking about how uncommon complex like might be.<br /><br />The universe is a huge place, and even if complex life is relatively uncommon, it could still exist on millions of planets.<br /><br />I also suspect it's Peter Ward's job to be disaster minded.James A.

It makes it more likely that we'll look after our own Earth.<br /><br />I'm also surprised that David Brin hasn't twigged to the notion that 'Rare Earth' should be the default. Such an attitude would make it less likely that people would shout (by high strength directed radio) into the wilderness thus calling attention to ourselves and potential aggressors, a precaution that David Brin has advocated.<br /><br />'Rare Earth' is also the more natural scientist's position. Why believe in Aliens when there is zero proof. Belief in Aliens is the Romantic position I'd have thought and anathema to a more Enlightened mind.<br /><br />I too would have loved to have seen that debate.David Ivoryhttps://www.blogger.com/profile/08570363230789488936noreply@blogger.comtag:blogger.com,1999:blog-1695280310697378421.post-67798922211876944292009-09-06T17:15:23.616-07:002009-09-06T17:15:23.616-07:00More and more I am inclining to the "rare ear...More and more I am inclining to the "rare earth" POV.

It's what you might call an error of scale. Nothing about the world, or the human race, as we know it today, is likely to be remotely recognisable even one million years from today, so just put the death of the sun out of mind. <br /><br />100 years - that's different.
