Only if it's cheaper. They said the same thing about plant based meat - and it hasn't because it's more expensive.

Plant based meats are 1) Still not real meat, hence is only considered by a limited target consumer 2) Is still relatively new to the mass-market. Hence still isn't at it's lowest price point.

My understanding is that subsidies also drive down the cost of meat quite drastically.

Hard pass. Let's see some long-term (10 years) test data first (e.g., how does it effect things like muscle growth/retention, fat growth/loss, cell function, cancer promotion/prevention etc). I'd put this stuff on the same level as any mass-produced junk (HFCS, seed oils, etc) that has already been proven to be harmful to humans long-term as a cautious default.

But keep cooking your steak in a pan filled of PTFE

Citing a likely dangerous thing that the FDA doesn't have any objections to is not a good counter.

For evidence, my extended family down here raises cattle to this day. It's hard to beat doing hardly anything other than let the beasts eat grass for a couple of years. Try to beat that for a cost of goods.

I have extended family doing the same in South Brazil. But those cows require a bit of care, a fair chunk of land, and release a large amount of methane. Lab meat will beat it in the end one day when all costs are considered.

When this technology finally gets there, and I see no reason to think it won't eventually, it will change the world so dramatically. The amount of land and water we won't need to raise animals or food for animals it's staggering. The amount of meat the world consumes will double by the end of the century (will it? I made that up). As the world gets richer, people eat more meat. Combine that with a rising population a…

Growing meat in an ultra-sterile environment using complex biologics, some of which the current source is to extract them from animals. I’d bet on fusion becoming mainstream first.

Soon it will only be cheaper if you're completely discounting the price paid to the ecosystem. In fact with a full accounting I'd wager it's already cheaper. How many unique species that evolved over tens of millions of years have been lost forever, in the last 50 years alone, due to clear-cutting in Brazil? How much clean water and topsoil has been polluted and washed away? How much carbon has been released? How muc…

Modern industrial agriculture, is what you are describing. It is very efficient form the POV of $/calorie. But it is terribly inefficient from a hectare/calorie. The purpose of modern industrial agriculture was to free up labour for industry. It has been a huge success in that. Applying technology to the food production system is IMO a good idea. I think we should be sensible. Using robotics and regenerative agricult…

> It is very efficient form the POV of $/calorie.

It's probably only efficient because farms don't have to cover the cost of their methane+CO2 emissions and water usage+pollution. I'd like to see these subsidies eliminated.

They could market this like crazy to the eco-conscious crowd.

A lot of inedible feed is going to be stuff like alfalfa, which is specifically grown as feed and whose farming has massive negative effects like starving the Colorado river of water [0]. [0] https://www.theguardian.com/environment/2022/sep/12/colorado...

Then we need to reassess water-use and water rights and let the market sort itself out. Make alfalfa farmers pay for water and send the cost down the value chain. Consumers will signal how much they are willing to pay, and producers will respond by reducing their supply.

I agree - currently a lot of farmers have essentially unlimited water rights, and they should pay the true price of water.

From first principles, it should be eventually.

Yeah I’m going to let other folks experiment with that for 10 or so years and see where it goes. I’m sure the meat is fine, it’s just a matter of not contaminating it during the process that I’m concerned about. The FDA is really poor at enforcing the health and safety aspects of manufacturing and processing. They simply don’t have enough inspectors and the inspectors don’t fine big offenders enough

If you put cattle on farmland, and utilize regenerative agriculture techniques, it costs a bit more, because yields aren't artificially boosted while destroying the topsoil. In return you actually capture carbon into the grasses from the atmosphere. That would normally just rot, but the herbivores digest it and make it bioavailable for the fungi and bacteria in the soil, where the carbon accumulates. The herbivores a…

I'm not entirely convinced by this argument. A lot of the ecological arguments against meat-eating is because cattle grazing requires huge swaths of land. Current practices generate this land via deforestation (I don't have statistics on how much land is generated via deforestation, but we can at least conclude that it's A Thing That Happens^{tm})[^1]. While certainly, grass captures some carbon, I'm going to guess that it's far less than a rainforest ecosystem of the same area, especially since the rainforest isn't being actively consumed. There's also the biodiversity of a forest environment.

If we go off thermodynamics there is a lot of energy being wasted in producing the meat, even if that energy isn't expended by those tending the cattle. To say nothing of the animal suffering involved, we currently expend ~10x the calories we get from the beef producing it (IIRC). If we could get even to 5x that'd be a huge environmental win. Edit: Looking it up, beef sits at 25x, and chicken 9x. So, a lot of room fo…

I think there is a big difference between intensive animal farming (growing animal feed like corn and soy to then grow animals with) and letting animals graze on natural grassland. For example grazing works in non-arable land (eg hills / mountains / rocky areas) and is therefore (I'm guessing) a more efficient form of food production for these areas than whatever else could be done there. On the other hand, growing plants on farms specifically to feed livestock, probably not very energy efficient compared to growing plants for direct human consumption on the same farms.
