It has often been said that, if the human species fails to make a go of it here on the Earth, some other species will take over the running. In the sense of developing intelligence this is not correct. We have or soon will have, exhausted the necessary physical prerequisites so far as this planet is concerned. With coal gone, oil gone, high-grade metallic ores gone, no species however competent can make the long climb from primitive conditions to high-level technology. This is a one-shot affair. If we fail, this planetary system fails so far as intelligence is concerned.

The High-Intelligence Life Forms of the planet, of which there were at least three species, all of low technological achievement, they would ignore or enslave or extirpate, whichever was most convenient. For to an aggressive people only technology mattered.
Ursula K. Le Guin
We may not appreciate the fact; but a fact nevertheless it remains: we are living in a Golden Age, the most gilded Golden Age of human history — not only of past history, but of future history. For, as Sir Charles Darwin and many others before him have pointed out, we are living like drunken sailors, like the irresponsible heirs of a millionaire uncle. At an ever accelerating rate we are now squandering the capital of metallic ores and fossil fuels accumulated in the earth’s crust during hundreds of millions of years. How long can this spending spree go on? Estimates vary. But all are agreed that within a few centuries or at most a few millennia, Man will have run through his capital and will be compelled to live, for the remaining nine thousand nine hundred and seventy or eighty centuries of his career as Homo sapiens, strictly on income. Sir Charles is of the opinion that Man will successfully make the transition from rich ores to poor ores and even sea water, from coal, oil, uranium and thorium to solar energy and alcohol derived from plants. About as much energy as is now available can be derived from the new sources — but with a far greater expense in man hours, a much larger capital investment in machinery. And the same holds true of the raw materials on which industrial civilization depends. By doing a great deal more work than they are doing now, men will contrive to extract the diluted dregs of the planet’s metallic wealth or will fabricate non-metallic substitutes for the elements they have completely used up. In such an event, some human beings will still live fairly well, but not in the style to which we, the squanderers of planetary capital, are accustomed.
Aldous Huxley
Our best destiny, as planetary cohabitants, is the development of what has been called "species consciousness" — something over and above nationalisms, blocs, religions, ethnicities. During this week of incredulous misery, I have been trying to apply such a consciousness, and such a sensibility. Thinking of the victims, the perpetrators, and the near future, I felt species grief, then species shame, then species fear.
Martin Amis
The trouble with the canons of scientific evidence [...] is that they virtually rule out the description of anything but oft-repeated, oft-observed, stereotypic behavior of a species, and this is just the sort of behavior that reveals no particular intelligence at all - all this behavior can be more or less plausibly explained as the effects of some humdrum combination of "instinct" or tropism and conditioned response. It is the novel bits of behavior, the acts that couldn't plausibly be accounted for in terms of prior conditioning or training or habit, that speak eloquently of intelligence; but if their very novelty and unrepeatability make them anecdotal and hence inadmissible evidence, how can one proceed to develop the cognitive case for the intelligence of one's target species?
