John Smart suggests (with reservations) that our universe is biased towards certain kinds of tipping points and against others.
This is a controversial topic, so I will mention it only briefly, but suffice it to say that after extensive research I have concluded that no biological or nuclear destructive technologies that we can presently access, either as individuals or as nations, could ever scale up to "species killer" levels. All of them are sharply limited in their destructive effect, either by our far more complex, varied, and overpowering immune systems, in the biological case, or by intrinsic physical limits—combinatorial explosion of complexity in designing multistage fission-fusion devices—in the nuclear weapons case. These destructive limits may exist for reasons of deep universal design. A universe that allowed impulsive hominids like us an intelligence-killing destructive power wouldn't propagate very far along the timeline.
This is a slightly more (pardon my French) "subtle and nuanced" statement than Rush made. Failure is not impossible, but the dice seem to be strangely loaded in favor of success.
I don't think it's so strange. If it were easy to destroy the universe, for example, then someone would probably have done it by now. So there's an anthropic principle at work.
But I don't see how John Smart can conclude that the universe is predisposed to preventing species destruction. First, our immune system is rather sophisticated, but we've already developed diseases that can overcome it. Similarly, I've heard estimates that a 10,000 megaton nuclear bomb surrounded by ample cobalt (one of the fabled "Doomsday devices") could effectively kill off most large animals (including humans) on Earth and poison the ecosystem for a while (radioactive cobalt has a half life of five years) though properly prepared, humanity could survive such an event I think. Both the US and Russia have sufficient nuclear explosive power to give this a try, but neither has shown any inclination to be this colossally stupid.
Claiming the existence of "deep universal design" seems a little premature in my opinion. We've steadily ramped up in explosive power to the fusion bomb. I think further development has been hampered less by complexity than by the impracticality of such a device. Both the US and Russia have enough destructive power to obliterate any combination of countries that they chose to. These devices have great strategic value. There's no incentive to make a bigger bang.
Instead, the value has been in designing more effective weapons (eg, "smart bombs") that deliver less force, but do so more accurately. In the various recent wars, the US has dominated through use of these sorts of systems rather than through it's powerful nuclear weapons.
I like the term "anthropic principle" because it has it's own best criticism built right into the name.
That criticism goes something like this: Of course it looks like the universe favors intelligent life from the point of view of an intelligent life form that's around to think about it. All those forms of intelligent life that would think differently are not around to voice an opinion. They didn't make it.
That said, it certainly seems that this universe favors the arrival of intelligent life in some form - if not specifically human intelligent life. The reasons why are worthy of another post (or a book or two).
I'm ready to start my own political party but I'm not sure what to name it. The Good Old Common Sense Party with a Dash of Bright Ideas, maybe.
I just hope the Universe isn't listening to the news lately and regretting favoring our arrival.
