Astronomical waste

Astronomical waste is the loss of potential value resulting from delaying the efficient exploitation of the universe's resources. The term and the concept expressed by it were introduced by Nick Bostrom in a seminal paper.^[1]

In relative terms, however, the costs may be quitepretty modest. The cosmos has existed for about 10 billion years, so one should not antecedently expect cosmological processes to cause value to decay by more than 1 part in 10 billion or so per year. And the observational evidence appears to be consistent with this prior assessment. The finitude, expansion, and burndown of the universe seem all to be occurring at a slow enough rate as to be in line with the estimate based on the duration of the universe so far.^[2]

If the opportunity costs of delaying the exploitation of the universe's resources are so lowsmall in relative terms, however large they may be in absolute terms, it follows that such costs are unimportant relative to the costs arising from exposure to existential risk, which are much higher in comparison. Over the next decade, maybe a billionth of total attainable value will be lost as a result of failingdue to failure to arrange the universe optimally. Over that same decade, perhaps a thousandth of this value will be lost in expectation from exposure to a 0.1 percent risk of an existential catastrophe. The costs from existential risk exposure thus appear to exceed the opportunity costs from delayed expansion by several orders of magnitude.

Thus, although upon first noticing the astronomical costs of delayed technological development an altruist may be tempted to conclude that such development should be hastened, that conclusion does not survive careful reflection. Because the bulk of existential risk is posed by anthropogenic existential risks from new technologies,technologies pose the bulk of existential risk, accelerating the development of new technology will itself have majorsignificant effects on existential risk. Such effects will dwarf any gains from reduction ofreducing astronomical waste, and should therefore be the primary consideration for decision decision-making.

Astronomical waste is often cited as a consideration in favor of longtermism. When authors talk about "astronomical waste" in these contexts, however, what they typically mean by that phrase are not the costs of delayed expansion, but the costs of failed (or flawed) expansion. Thus, Carl Shulman mentions "the expected Astronomical Waste if humanity were rendered extinct by a sudden asteroid impact." (Shulman 2012)^[3] Similarly, linking to Bostrom's paper, Gwern Branwen writes that "human extinction represents the loss of literally astronomical amounts of utility." (Branwen 2020)^[4] And Siebe Rozendal writes that "Extinction would be an ‘astronomical waste’." (Rozendal 2019; see also Dai 2014, Lewis 2018, and Kristoffersson 2020)^[5][6] The expression astronomical stakes (Bostrom 2015; Wiblin 2016)^[7][8] may be used to express this idea, while reserving astronomical waste to refer to the  opportunity costs of delayed technological development.

The accessible universe is vast, and virtually all of it remains unexploited. The Virgo Supercluster contains 1013 stars, and the energy of each star could power 1042 computations per second. The human brain can perform about 1017 computations per second. Assuming that the morally relevant properties of the brain—such as phenomenal consciousness—supervene on its functional organization, it follows that the universe could support, every second, an amount of value equivalent to that realized in 1013times×1042div÷1017=1028 human lives. The moral costs of failing to actualize this potential thus appear to be enormous.
