@domitron Good points, however it is a statistical fact that the more advanced a society becomes, the less its population grows. This is evident in industrialized nations all over the world...in fact Japan, who is arguably one of the most technologically advanced, is actually showing a decline in population due to low birth rates. Of course this is all due to many factors, such as but not limited to less of a need for large families for things like farm labor, advances in contraception, the reality of most families now having two working parents with less time for child care, and as harsh as it may seem but true, with much lower rates of childhood disease and death, families in modern society have less of a need to "have more because you might lose a few".
So that all said, your point is certainly valid, but could you see an eventual turnaround as more societies on this planet become modernized, rather than a population explosion? I mean of course this will take awhile since much of the world's communities are lagging far behind others, and of course we are certainly in a major upwards population trend now and for the foreseeable future, but EVENTUALLY... assuming we don't all blow ourselves up before we get there? Maybe overpopulation is a Great Filter we need to overcome?

@nickkk420 Yes we did, and I owned a couple 80's and early 90's vehicles that got high 30s and even 40s for mpg. However they had around 70 and 90 hp. Yes they were light also, but of course they predated all the requirements on current safety features (airbags, etc). Also they had all the joy of driving as a lawn mower. Both were manual transmission, which made them a little more responsive, but they were still SLOW, and in the fast paced world we live in today, your typical consumer wouldn't want one. That is our problem. We want efficiency, less pollution, etc, but we also want our 400hp land yachts with 18 tv screens and every other tech gadget we can imagine that all adds weight. Heck, in my '85 Civic, a cigarette lighter was an OPTION (mine didn't have one, or any DC port of any sort!)

@domitron Interesting stuff and good discussion. And yes, of course there is the "political" element to all of this. I've heard the "chemtrails" theory thrown about too, it's more or less tin foil hat stuff. You get the religious extremists that believe they should have 27 babies because "God wants it that way", and others (I really don't know how to classify them,) that view humanity as some sort of cancer on the planet and we should all consider not reproducing. And those that say "the government wants to kill us all" really aren't stopping to think about that more people mean more tax revenues, so why would they do that? You mentioned that as well. Of course there should be middle ground on all of this. I think as a species we have a long way to go, and what I comes down to is will we survive long enough to reach that point. One thing I think (and hope) comes with that maturity is things being less politicized. Like for example, maybe we should just be responsible, not waste resources, reuse what we can, etc, not for a political cause but for our own well being.

Resources are going to be the biggest hurdle to galactic domination. Sure, once you're out there in space you have lots of resources at your disposal, but getting there is going to be very hard, even if your technology is very advanced. Just think about the materials, the cost, the man hours, the planning, the building, of just one space shuttle or one large telescope. Now think about orders of magnitude greater. You aren't going to get far in space in a tin can. Could you even obtain the resources to build large space faring vessels, or solar collectors to power everything? That's more heavy metals than are in the earth. So just mine some asteroids? Well you need to make all the equipment to not only do that, but to get there, and it's all going to need power as well. Not saying impossible, but extremely difficult and maybe just the fancy of science fiction.
