This is incorrect. Every economic output requires material inputs. > I can create digital goods and services which people buy Your digital goods and services

This is incorrect. Every economic output requires material inputs. > I can create digital goods and services which people buy Your digital goods and services require physical machines to run on. These machines are made of physical materials, including some rare earth minerals that are costly to extract. These machines require energy to run, which also requires material inputs. > I can even give massages all day, and this also doesn't destroy the environment Human beings like yourself require material inputs to live – food, shelter, energy, to name only a few. Just by being alive on a biosphere, you are impacting the environment in some way. The size of that impact depends on your individual lifestyle. There is simply no such thing as "immaterial" economic production.

Ahh but those machines are constantly becoming simultaneously more efficient and more powerful. And soon enough they'll all be ran on renewable energy. OP said nothing about growing the population. His statement can be true even as world population growth is slowing. Like many things, there may be no purely immaterial, but there is much (and increasing) practically immaterial.

  we need to build the first solar power plant only using the output of a smaller solar plant, so electric digger, hydroponics for food, electric smelters etc. after that it's all downhill.

> This is simply incorrect. Every economic output requires material inputs...There is simply no such thing as "immaterial" economic production. Parent post was talking about marginal cost of production. E.g. where once we'd buy servers to run services on, we now share servers rented "by the cycle" from providers who amortize the cost over many users. Idle servers can be running at-the-moment economically valuable code for others. It's even possible that some economically valuable computation I might cause to be performed could consume an immeasurably small amount of power compared to the server sitting idle. Your formulation reminds me of the "labour theory of value" (https://en.wikipedia.org/wiki/Labor_theory_of_value https://en.wikipedia.org/wiki/Labor_theory_of_value).

  i'm partial to the labor theory of value, not for pricing (which is better modeled with marginalism, as you speak to), but for an intrinsic value by which we can evaluate how well a particular market might be working. a well-functioning market should tend toward the intrinsic (labor) value of a good (if, for example, relevant information is widely available and known, competitors can easily enter and exit, distortions are minimized, etc.).
  - G_T_T 7y ago
    How do you determine if the market price is tending toward the labor value of a good if there is no clean way to map from labour-hours to prices?
    - clairity 7y ago
      that's the whole point though. price can be highly decoupled from cost, which i'm positing is a signal of the magnitude of the distortions in a given market. but to your question, you'd just "measure" price as the prevailing price that you see in the marketplace, and labor is measured as the aggregate cost of all labor inputs, including parts and raw materials and amortized capital costs. in a well-functioning market, you'd expect prices to trend with the labor value. the industry profit percentage would then be an reasonable expression of the riskiness of the market/industry (in drug discovery, it might be 50% but in grocery, it might be 5%). so for example, if apple sells iphones for $1000 but it costs them $400 in labor to make and sell, their labor-price markup would be 250%. in a functioning competitive market, you'd expect a competitor like samsung to pursue those profits and, as a result, eventually drive prices down.

While your point is true on a basic level, I think The parent’s point is on to something. There must be a level of economic production that falls below the level of emission that can be absorbed without contributing to climate change. Furthermore in <1billion years everything on earth dies anyway (due to an expanding, ageing, sun) - so it is sustainable to use <1billionth of non-renewable resources.
- qsymmachus 7y ago
  > There must be a level of economic production that falls below the level of emission that can be absorbed without contributing to climate change You're right, there absolutely is such a level. The important point is that to stay at or below that level, you have to give up on the idea of perpetual, infinite growth. The inputs and outputs must remain constant. My point was that there's no such thing as "immaterial" growth, so we can't escape this limitation by making a bunch of apps forever.

    Without growth above the population growth, life becomes zero sum or negative sum. That means that taking and fighting becomes more rewarding than building. It is either growth or war, no way around it.

- swid 7y ago
  It does though. Proof (if you want to call it that, I accept it is not formally valid) via contradiction: There is the immaterial economy which which might theorize can perpetually grow. There is also the material economy which is rooted in real physics - ie, materials, energy (it will always take some energy to heat up water and prepare food, for instance). Can we rule out that buying metal and building material become completely free? Or that the cost of energy will be reduced to zero? If there is limited supply, there must be some cost and if that cost is too low, someone will buy it up, corner the market, and start charging the correct price. If so, the material economy cannot grow forever (outside inflation, which is not real economic growth). If the material economy cannot perpetually grow, but other parts can, then eventually that part of the economy will completely eclipse the non-material economy. As the part that perpetually grows goes to infinitely, the relative value of the part of the economy rooted in physical limits will be worth relatively nothing. Which contradicts the earlier point part of the economy can perpetually grow when some parts do not, unless the parts which cannot perpetually grow simply become free.

A desktop from a decade ago can still run productivity software, especially if you run Linux or another operating system that doesn't cut off support for non-technical reasons. It is true that some physical resources are going to be required e.g. electricity - but in general we are wasting tons of precious resources building "disposable" devices like cell phones that are used for only 2 years to do tasks that have little economic value. If we actually used hardware for more of its usable lifetime, we could greatly reduce long-term environmental costs.

  >but in general we are wasting tons of precious resources building "disposable" devices like cell phones that are used for only 2 years to do tasks that have little economic value. This is wrong in two ways. 1) Cellphones don't just last 2 years; lots of people have older models. Sure, a bunch of people get rid of theirs after 2 years, but then they go to the secondhand market, where people like me buy them for a small fraction of their original price and keep them for another year or two before reselling them. Frequently, older phones eventually find their way to developing nations where people can't afford the latest iPhone. Your argument sounds like someone whining about people leasing a car for "only" 3 years; what do you think happens to cars after the original owner trades it in? As for "little economic value", that's just plain ridiculous. Smartphones have enabled all kinds of things that just weren't possible or easy before: managing your bank account remotely, sending money to people (e.g. Venmo), GPS navigation, communicating without playing telephone tag, etc. And they do it with much less energy than any PC uses.

    > 1) Cellphones don't just last 2 years; lots of people have older models. Sure, a bunch of people get rid of theirs after 2 years, but then they go to the secondhand market, Increasingly less so. On one side, you have cheap subscription plans that bundle usable (not too decent) phones, on the other hand, phone life is shortened by a combination of planned obsolescence, software bloat, and lack of security updates. Short sales cycles is what manufacturers plan for and actively work towards. > Frequently, older phones eventually find their way to developing nations where people can't afford the latest iPhone. I might be wrong, but I'm not convinced. Shipping costs money, phones are cheap, and both battery and flash memory have pretty short lifetimes now. A good chunk of phones are barely operational after 2-3 years. RE benefits of smartphones, it's all true, but you can't run economic growth on it forever. Smartphone transformation happened. It's mostly done. Itself it won't fuel further growth. Production of hardware and software might, but that is not free in terms of energy/resources.

that is a shortsighted reading. OP's job could have shifted from e.g. "driving a heavy truck all day for my plate of food" to running a program on a computer which generates only a miniscule fraction of the emissions. As such , the economy overall has become "greener" for equal benefit.

If I sing beautiful songs on the street, that has a material value one could measure. It represents economic growth compared to a world where I do something unproductive, like arguing basic reasoning with people on HN. It does not, however, require more input materials. I swear, one day I'll find out why the software crowd, of all people, is completely incapable of understanding the difference between "material" and "real".
samsonradu 7y ago
Not only this but you must also take into account the source of the money that buys your digital goods. There is a strong correlation between the environmental cost and economic growth. It might weaken but it will never be decoupled, as long as people do have 'material' needs.
andrewmutz 7y ago
You haven't rebutted the parent poster. He said "Some people say growth can't happen forever, and all growth comes at environmental cost". Pointing out that "Every economic output requires material inputs" doesn't mean that there are limits to growth or that you can't have growth without environmental cost. As an example, if you have a resource that you consistently get more efficient at operating, you can consistently use it to provide more and more value to the world (economic growth). To use his example: if you take a human who would be using material inputs like food, and instead of them engaging in activity that did not provide value to society, they spent their time giving people massages, you have not increased the amount of physical resources being consumed (since the person was otherwise using the same amount of resources, just not doing anything of value).
- TeMPOraL 7y ago
  This is an accounting trick, though. It works because people are willing to pay for a massage and not for whatever the person was doing. But to actually grow the economy, you have to continuously retask that person to ever more profitable activities. You can also create growth by moving money in circles increasingly fast. Question is, how far we can push bullshit jobs before people get fed up with it? I'm not convinced that "forever" is the answer.
  - andrewmutz 7y ago
    It's not an accounting trick. Different ways a person spends their time genuinely provide different levels of value to society. If a doctor spends his time saving lives or spends his time watching television, the impact on the world's material resources isn't that different, but the amount of value to society is much greater if he is saving lives.
    - TeMPOraL 7y ago
      Again, to have economic growth you actually have to have growth. Once you get everyone doing the things that yield maximum economic value, you no longer have growth. You'd have to make more people (exponentially, under current economic regime), which costs physical resources. As an aside, when talking about economic growth we're looking at economic, not social value, and it so happens that saving lives is one of the less valuable things. You can determine it by looking at the paychecks of doctors or ER personnel.
