Hydrogen Direct Reduction ❌ EVs Powered by Fossil Fuels ✅

The kicker is we need agriculture and industry, like it or not. Whereas no one apart from some billionaires and tech bros want or even need AI.
I mean sure. But we don’t really need to torture animals, which is the big part of the emissions. We just like it a lot.
Username checks out.
Now I feel bad because I used the same line on them too. Poor person probably constantly gets this as a reply
%80 of agriculture is animal feed. Not saying everyone should become vegeterian or vegan but I think the culture that pushes more than necessary animal based products (especially America) should be suppressed gradually.

Those percentages don’t really add up to 100, though.

Something like 40% of American corn is used as a feedstock into ethanol fuel production. But that just strips out most of the starches and carbohydrates for fermentation into alcohol. The remaining proteins and fats are used mostly for animal feed. And somewhat surprisingly, the captured CO2 is sold as an industrial CO2 product, such as dry ice. So for that 40% of corn, we could say it’s used for ethanol production. Or we could say it’s used for animal feed. Or other processes. But it’s really all of the above.

Modern American corn and soybean farming is just basically efficiently producing a bunch of bio feedstock into whatever processes can make use of those products, whether for human food, animal feed, industrial processes, etc.

Good point, however how much of feed agriculture does this sort if “feed from secondary products” make? It definitely helps that they produce multiple products from a single type of feed. Would also like to know if a person exchanges a part of their animal product diet with plant, does this actually reduce required farm land (after all then you need to produce more vegetables for the said person).

According to this analysis (probably a biased/motivated source but not one worth lying about actual output for its members to make economic planning around), each bushel produces 2.9 gallons of ethanol, 14.5 lbs of distillers’ grain, and 0.9 lbs of corn oil.

Distillers grain is a pretty useful animal feed, with about the same amount of calories, and a higher protein content, than regular corn per pound.

So if a 54 lb bushel of corn that has been used for ethanol production still has about 14-20 lbs of grain equivalent (depending on how important that higher protein content is for the animals being fed), then some percentage of that corn being used for ethanol should still be counted towards animal feed. Depending on how you want to account for the oil, too, there’s probably some feed value there, too.

extraordinary claims require extraordinary evidence
This is common knowledge by now, see for instance.
Half of the world’s habitable land is used for agriculture

More than three-quarters of global agricultural land is used for livestock, despite meat and dairy making up a much smaller share of the world's protein and calories.

Our World in Data

first, this relies on poore nemecek 2018, which used poor methodology, so you shouldn’t believe the study you cited.

but beyond that, much of that farmland is grazing land. that’s not 80% of agriculture, it’s 80% of agricultural land.

Yeah agricultural land was what I tried to convey as well, fixed thanks (not necessarily land that is agricultural for human edible vegetables though).

71 per cent of EU agricultural land used to feed livestock, says Greenpeace report - BBIA

Greenpeace released a report on 12 February 2019 on how public funds delivered via the EU’s Common Agricultural Policy (CAP) are currently used, finding that around 71 percent of EU agricultural land is used to feed livestock.   When excluding grasslands and only taking account of land used for growing crops, the report concludes that [...]Read More... from 71 per cent of EU agricultural land used to feed livestock, says Greenpeace report

using land to make food is good, actually.
Potentially yes but I think if it is always the same type then it deprived the land of certain types of nutrients. You need to rotate the crops.
if you’re planting crops, sure. if you’re grazing grasslands, the story changes, and that’s most of what agricultural lands used for animals are.

The problem is, the models are really good at some things. We’ve been using these things since before chat gpt hit the market. It’s identified tumors, cured a dog of cancer evidently, and with adversarial training beat the AI that beat the chess master in a matter of hours.

This is one of those disruptive technologies that isn’t going back in the bottle. We’re stuck with this crap.

(Note: I was convinced the dog cancer vaccine thing was bullshit but there’s quite a bit of actual data, a fucking tech bro actually did it.)

Of no, a nuanced and grounded take on LLMs! Everybody get your pitchforks and downdooters!
