  • Not all the matter in farming fields come from fertilizer. A lot of it comes from CO2 in the air, which will eventually go into some plant that we can eat. Also, all those ways that matter is lost, therefore not being 100% efficient doesn’t make matter disappear. Burning turns it into CO2 -> it will reach a plant. Excrements going into water streams -> plants will pick them up, or ocean wildlife will pick them up. Buried corpses -> microbes and plants will pick them up. The only way to “lose” matter is for it to leave the atmosphere into space or to be buried so deep that no life can reach it.

    The atmosphere loses matter at a rate that is (presumably) not affected by human actions.

    Matter buried too deep is compensated by matter coming out from volcanic eruptions.

    As long as the earth’s core is hot enough for volcanic activity and the sun doesn’t run out of fuel, the cycle keeps going.


  • If you place a data center in a 100% green location, then you’re reducing the supply of 100% energy, so everything else has to consume less green energy. Therefore, by using 100% green energy you just increased your carbon footprint.

    Green energy, like all resources, is limited. If you waste it on a glorified food predictor you can’t use it on a electric harvester that will feed the people.

    Even if you want to avoid this problem and create your own green power plant for your own data center (creating the green supply and demand at the same time), you are still spending green energy resources (rare metals and manufacturing capacity) that went into creating your powerplant instead of creating a powerplant for electric harvesters.

    There’s no way around it. Misusing electricity is accelerating climate change, one way or another. Even if the energy you are misusing is 100% green.

    Just because it’s open source doesn’t mean it’s good. Also not every situation is the same. Using Linux instead of windows has advantages/disadvantages very different than using crypto instead of fiat.

    I can think of thousands of reasons to pick Linux, thousands to pick windows and thousands to pick fiat. I’d have to think real hard to even think of a single reason to pick crypto over fiat.





  • Because the day and year have meanings. They are “the time it gets for the earth to make a full rotation” and “the time to come full circle around the sun”. They are of varying length, so we actually use time periods that are almost the real day and year, and call them day and year. These are fixed length.

    The second is arbitrary, because we just arbitrarily decided to split up the day in 24 hours, hours into 60 minutes and minutes into 60 seconds. Why 24/60/60? Kinda arbitrary.

    Now, does arbitrary mean it’s bad? I don’t see why. The meter is defined in a similar manner, but using multiples of 10 instead of 24/60/60.

    I know the meter and second have been redefined to be based on scientific phenomena and be independent from the earth, but their length has the same arbitrary origin. And as such, they are arbitrary.

    I don’t see what being arbitrary has to do with being a good or bad unit of measurement.



  • I see you completely ignored my comment. The problem is not the amount of electricity used in itself, which the estimate of 6GWh-130TWh is as precise as shooting a dart at the moon.

    Crypto uses energy for the sake of using energy. The value of crypto is based on the amount of energy used to create it. It’s not valuable to society. That’s what people is upset about. Crypto provides even less value to society than ads do.

    Even you said it, ads spend energy because they employ people, those people generate value.

    That’s like saying we should stop heating homes because it consumes more energy than crypto mining. Hose heating improves the quality of life of people. Crypto does not.


  • With the electricity used to validate a single crypto transaction you could do thousands or even millions of DB queries.

    Yes, everything uses electricity. That’s like saying that it’s fine if you kill one cow per day to eat its ear and throw the rest because hundreds of them are killed every day in farms.

    Wasting so much electricity in such a non efficient manner so a decentralization cult member can have his wet dream of using non-government money makes no sense.


  • That’s because ad serving doesn’t set a lower bound on the electricity price. The value of crypto and the value of electricity are linked.

    For the sake of simplicity I’ll just say Bitcoin.

    If the price of Bitcoin stays constant (big if), and the rate of Bitcoin per watt does too, then everyone would start mining until the demand for power is so high that the price increases until it’s as high as the Bitcoin per watt.

    Sure, they are unrealistic assumptions, but it’s easier to see this way that the value of Bitcoin is (almost) the same as electricity. If it were lower, noone would mine it, if higher, people would buy electricity with bitcoin for a profit until the 2 equalize.

    Electricity will never be much cheaper than Bitcoin, market forces will make sure of that, causing a huge environmental impact. Ads, however, only use as much electricity as they need to operate, their amount is not decided based on how much electricity they waste.
