Yep, nothing gets me salivating as much as the idea of a digital Euro issued by the EU, implemented to be fully private (can't see sender/receiver/transaction count/transaction amounts), bulletproofs [0], combined with v

Why would that be a solution if you still need to manage manure to grow plants? You would still have runoffs due to similar mismanagement. It's not the management of human wastewater that is an issue with ocean deadzones.

To me it sounds like: 1. anything humans decide to do should be accepted because of invisible positive outcomes (who could have predicted Internet from oil combustion), 2. the moment negative outcomes become visible, let's wait until i

I do not understand how cities are blamed when a farm with 2500 dairy cows produces similar waste to a city of 411,000 people.[0] Cow poop is destroying the oceans due to massive amounts of mismanagement or just floods. Just goes to show th

I don't care about models. I care about variance. The additive nature of climate change means that there is no variance in the other way. The effect size does not need a model of time for it to be determined worrisome. Permafrost is sp

The thing about these models is that they are not necessary if you want to understand the magnitude of change. For example, we can estimate correctly (within the same order of magnitude) the emissions of CO2 equivalent gases a year that we

I agree. I've been naive at the beginning of my career, thinking that a great product sells itself, but it's simply not true. There's so much trash everywhere that is earning millions (book reading apps, silly chart-db softwa

Temple Grandin's corridors provide a stress free roaming path for the cows that feel the urge to be milked. The corridor ends with a proper curve that makes the cow stop right above the ground mounted camera that is trying to capture t

1g of protein per 100mL is not as much as cow's milk. Although, human milk also does have around 1g of protein per 100mL, so I guess it's fine for toddlers.

When it comes to price, that's what government subsidies do for the cow's milk and high demand does for the oat milk. Although, I've seen Temple Grandin's methods live and a milk farm with milking robots basically runs i

Another side of the coin, the cow milk production obliterates any savings on transport of the milk to the consumer. It's one of the most energy intensive ways to produce food. (impregnating the cow every year, feeding the cow to suppor

But if we are arguing if waste is justified then obviously it's not for you or me to decide if it is, including the humans from the future. I'm just laughing at the inconsistency. If people were really consistent in their views of

Valid argument for what? Humans around the world are consuming food, heating/cooling themselves, all in the service of some gamified activity. Some of these activities are as useless as mining Bitcoin. Yes, these activities aren't

Concorde is fine. The LK heuristic was published in 1973. After that, until the mid 90s, no one could outperform the original published results with the same heuristic.

Absolutely, that's exactly the answer to the guy talking about "wasting energy" on Bitcoin. On what else would we waste it then? Energy is being wasted everywhere on much sillier things at much grander scales.

Well, from my perspective, a bunch of us are playing some very weirdly human constructed game of wasting life years on work and passive content consumption. If we ever make it to a cashless utopia, I'm pretty sure someone's going
