I think I just gained more appreciation for how complex but smoothly we are able to move 10 billion pounds of meat in America.

As a microbiologist, I cannot begin to express how much I appreciate the extent of how you stressed what an obstacle it would be to keep such a large environment sterile 24/7. Cell-based meat will never, ever be the same kind of thing as some guy taking up a side-hobby of brewing up Schrader Brau in his garage. Brewing not only allows for the growth of microbial life, but its success is based upon creating an evironment for their specific strains of fermentative yeast to thrive. Meanwhile the environment for cell-based meat is just a million-dollar bacterial culture waiting to happen. Mass media only seems to remember the existence of microbial life when the 1%ers decide it's time to crush what remains of that pesky middle class, I guess.

I work in pharma and I specialize in microbiological control. They neglect to mention that these bioreactors aren’t the real cost here. Cells need to be grown in highly controlled environments. These facilities will need expensive hvac and air filtration setups, disposable protective gowning for each employee, and rigorous quality control testing. These are all recurring costs that would balloon the final product cost. Of course the standard for food aren’t as high as for drugs, but when working with unproctected cells, it only takes one microbe to spoil tens of thousands of dollars of product

It's so crazy how much money is put into "solutions" to problems which are created by big corporations and monopolies. And then the same corporations and monopolies put the blame on the consumer and not on their own business practices...

...lets just call it what it is... a scam.

Salmon roe in orange juice is probably the grossest illustration for cells sitting in urine. Nice work

Listening to all the sanitation regulations regarding lab meat, it’s also the same fallacy regarding bug meat: you can’t just throw a bunch of random roaches in a blender, the meat being cultivated needs to be properly regulated and sanitized so that come to production, you’re not at risk of getting any food poisoning or worse.

Never trust anyone who tells you that you’re in extreme danger unless you give them your money.

This makes me appreciate how much animal bodies work to keep bacteria from interrupting cell grow and function. It's easy to take for granted but as soon as those cells are separated from the many, many layers of immune system, it's very clear how much we rely on it

It's almost like life has spent billions of years optimizing the most efficient method to continue itself.

I would not eat lab meat if it were free.

Considering they still haven't been able to replicate formula with the same health benefits as breast milk, I can't imagine that lab-grown meat would be as healthy as natural meat.

When I was growing stuff in a lab way back when, we grew it in Bovine growth serum (BGS) which is basically cow juice. This still requires cows to be "juiced".

I would like to point out that rest of the cow is not just thrown away after getting the meat from it. Almost entirety of the cow is used including bones and even manure. Artificial meat would force lot of other industries to adapt meaning cost of the steak would be just small part of big issue

If only they used their resources, talent and effort to make lab organs. So many people could benefit from this.

I think the closer we are to natural food, the better off and more environmentally friendly we are.

I've worked with cells, and it is no joke that those things are monstrous PITA's, despite their small size. The broth itself is 1 issue. In the lab, you have to monitor growth conditions, extract spent growth media, rinse cells with STERILE fluid, apply new growth media, do cellular checkups for abnormalities, and then -- praying to the lab gods -- hope your cells turn out. That stuff counted for a large portion of my grade in the final exam of the class. Still remember one of my dishes of cells being little SoBs. They gave me a not so subtle..., ahem, "go eff yourself" when they turned cancerous and said cancer cells looked like a phallic symbol. Right now, as it stands, lab grown meat is not viable. It's just a proof of concept. We need massive discoveries in cellular growth technology to expedite the process, enhance it's potency, etc.... It will require years of research + massive funding to develop the tech proper. Again, what we have is just an expensive proof of concept. My hope is that on our way towards lab-grown meat, we can use our advancements to create newer methods for people that need special treatments. Cancers, birth deformities, burn patients, and more could benefit from the tech. It would be wonderful if we could take a(n) technique/idea in that division, applying it towards burn ward patients. Imagine the potential at a well-stocked, well funded hospital. We could have a broth/stock mixture in a vial, use a patients undamaged tissue cells, combine the two, and use 3D printing technology on organic polymer sheets aid in recovery, said layer impregnated with a diverse cocktail of necessary nutrients to speed up recovery. Anyways, I do agree we're too optimistic, but we shouldn't stop trying.

Beans, bugs, and lab sludge. Two all bug patties, special sludge, lettuce, synthetic cheese, pickles, onions, on a gluten free bun.

Talking about genetically modified foods, I have gripe about 2 of them.1 is apples that are flavorless granny Smith tart apples from Walmart as well as many other if their fruit and vegetables are bland and flavorless. 2 is the way they are procesing Maxwell house and folders and other brands. I have been drinking coffee daily for over 59 years. It's not the same. I'm not sure how they are doing it but it tastes like they steam and extract the flavor from the beans (there is a need for coffee flavoring and caffeine they can profit off) and it also tastes so bitter as if the are grinding the the coffee bean leaves and stems to make the weight heavier to get a bigger profit.

I love how scientists say we need to reduce carbon emissions from factories and change agricultural practices. So some A hole comes out and says "No actually we need this product that isn't sustainable but fits the narrative"

I was fantasizing about making lab meat as a teenager in the 1960s. I was a big fan of science fiction and space exploration and I was planning to become a biologist. I was also interested in economics. Lab grown meat seemed like a normal extrapolation of technology; it did occur to me that steaks are more than a collection of cells but I didn’t think too hard about that.

Honestly the whole lab meat question is quite simple. It's a science that needs more development. It's not ready to be applied. It doesn't matter how badly some greedy people want to make money of it, it needs more time and work before it can actually function at all.

There’s a documentary on YT that interviews former Slaughterhouse workers. They’re all traumatized and depressed from having to to what they did. It’s soooo easy for us to just walk into a supermarket and purchase a piece of steak without having to deal with all the Insane Nastyness that is the Meat Industry. I don’t know if this Lab Grown Meat thing is going to be the solution but something has to change. Also people say it’s nasty as if they weren’t chugging down hot dogs, burgers, chicken nuggets and all sorts of processed disgusting crap down their mouths.

Fun fact: methane emissions from livestock is so small compared to everything else it doesn’t even matter. It’s just a scapegoat so humans don’t have to blame themselves. Also, all the land that we raise livestock on is actually land we can’t grow crops on. In the future, when farmers try to grow stuff on livestock land, they are gonna be hit hard by the reality that swamp/marshland and rocky soil is shitty for crops

Considering that people can tell the differences in taste between two similar animals that were fed on completely different diets during their lifetimes, I don't think anybody will be fooled by anyone trying to sneak 'cell-slurry' into their gourmet experience.

11:35 - That's something that bugs me about lab grown meat. In real meat, the nutrients in it depends on how the animal was raised (what it ate, did it get enough sun, etc). How are they going to replicate that? Are they just adding supplements to the meat? I'm tired of hearing "but animal take supplements too" instead of an actual answer.

It just sounds like another typical cash grab by greedy corporations. Seems impracticable to do this on a mass scale

Paid for by the meat and dairy industries

Basically, it's ultra processed garbage.

As someone who brews his own mead, I can confirm. There are all these tiny lifeforms in there, fighting each other. You want yeast to win.

Your video is full of errors and you make a lot of claims without citations. Please read the cultivated meat LCA report. David Humbergs "analysis" is an opinion piece and is based on false assumptions on the current practice of lab grown meat. You have a lot of reach and therefore you should back up your claims instead of spreading misinformation to 400k people.

my family owns a brewery and the reason why its easier to brew beer than grow cells is because yeast does the work to eliminate competition during its ethanol fermentation, coverting the sugar to ethanol which eliminates other bacteria and fungi. cells dont have that and are quite defenseless.

For lab grown meat to work, each bioreactor needs an autonomous mechanical liver, an autonomous mechanical pair of kidneys, an improved oxygen delivery system, an autonomous waste disposal system, and an artificial immune system. At that point you might as well just use what nature gave us and have a cow.

If you want to secure food production it makes no sense... But if you want full control of it...

What was the cost of the 1st computer?

Personally, i don't care about its cost or carbon footprints. I just want a world where intelligent animals don't have to live a horrible life and death

I usually get skeptical (and you should be too) about claims that an artificial process would be better at creating organic matter than nature.

Wait for Brad Pitt or some Kardashians to make an ad eating it, and everyone will jump in the hype train.

Theranos is a clear example that investors often have no idea if what they are investing in is feasible or not. But they have oodles of money to gamble on so just dump cash on some plausible ideas and hope one of them strikes you rich (er).

I think that the greater issue is that we're focusing on replacing cows instead of looking at actually environmentally impacting sectors. Instead of replacing all cows with artificially grown meat we could easily alternate to more energy efficient renewable sources. Windfarms, solar panels, geo thermal powered stations, hydro dams and other hydro related engines. Even nuclear assuming that it's not near high geologically active zones. Penalizing companies for their Co2 emissions, reducing the cost of electric cars whilst increasing the cost of diesel and petrol cars so that they can be powered by the renewable sources. These are the actions we should be taking but instead governments, oil lobbyists and politicians are looking for an alternative wonder drug to solve their problems. Changing from traditional beef sources and replacing them with lab grown alternatives, even assuming it did reduce emissions, wouldnt stop companies from continuing to create pollution. In fact, I'd wager their pollution production would ramp up because they now have more wiggle room to work with, invalidating the efforts to curb emissions. It's kind of like the difference between having $100 and thinking that you have that money spare, vs having that money to spend. Companies will look at the new emission freedom as extra space to use, rather than operating in their current restrictions.

It is ironic that people are so suspicious about people tinkering with their fruits and vegetables (this they choose organic), but when it comes to meat, it can be grown in a lab and that is fine.

No. I'll raise my own grass fed cattle before I buy this.

It's worth pursuing this as research still, in order to pave the way for the distant future. Though I admit we won't see it work on any real scale during our lifetimes.

To be fair, aviation travel used to be insanely expensive, but with technological advances related to aircraft engineering and oil mining efficiency, prices for air tickets went down to what we know today. Next generation sequencing of the human genome used to cost $100 million 20 years ago, but today it's only $1000. I think the cultured meat story is too early to call.

I can't believe that people still think that lab meat is a healthier option than regular meat...

Just imagine that there was a compact laboratory for the production of meat, with protection from bacteria and viruses, mobility and low cost... Wait a minute.

"Meat is unsustainable" ???????????????? If meat was unsustainable, there would be no living carnivores on Earth, including us.

The best way I could see lab-grown meat being viable, is simply growing the whole animal in the lab via methods like primitive cloning. But then, that's just a really complicated and likely really expensive way to do what we're already doing!

The first time we sequenced the human genome, it took 3 billion dollars, now it's down to 600 and still falling.

So it turns out that you need an entire organism to grow an organism. Who could have forseen this?

We will soon have a "saved environment" with an incredibly sick population 😢

That's why people need to read ingredients and where it was made .. I always read on every food package.

They know it’s a scam, you know it’s a scam, they know you it’s a scam - but there’s nothing you can do about it

It makes more sense to let people keep chickens, goats, rabbits, sheep, pigeons and cows - depending on their home size. In Egypt people have kept chickens and pigeons on apartment building roofs. It also makes sense to encourage growing vegetables, fruits and nuts over lawns.

So what you're saying is, we tried to do nature better than nature and failed. Who would have thought millions of years of evolution would actually be *checks notes* extremely efficient?

There's also a moral argument to use lab meat instead of real meat. Factory farmed animals are treated extremely poorly, so even if it's not better for the environment, there are still valid reasons why lab meat might be preferable.

This certainly makes me appreciate natural biology more

Ill stick to real meat raised on a farm. Support your local farmers and dont waste time or money on this chemical slurry.

Why does everyone forget the important point for why this should be a thing, like you know, not killing animals?

Where are the waste products of this industry going? What happens to the remains once a not-chicken nugget is created? There has to be hundreds of gallons of waste water and cleaning products going somewhere. Processed on site or down the drain?

whenever I get excited by new advancements in Science, Medicine and Technology; and then a bunch of rich and powerful soulless people and corporations start pushing said advancements like their life depends on it: I start to wonder whether they really want to improve our lives or just line their pockets and lead us into a dystopia

I worked in biofuels industry for 7 years and this is exactly the same reason why that also failed Biological limit and economic cost

Imagine a biological factory that able to process grass into biomass, and also the same desired meat allowed it to move it around to food sources to grow bigger or transport it elsewhere for sale or slaughter. And same factory also produced tough skin to protect it that could be processed into leather. And also said factory reproduces into other factories that grow to be just as large Oh yea thats a cow.

1:45 under estimating how much water and power is used on a daily basis, cows are not immune either

Another thing people who are into lab meat and eating bugs forget about is manure, which is still needed in agriculture whether we farm animals or not. Without organic matter, soil is degrading quite fast.

Singapore is probably not doing it for environmental concerns, but rather, for the simple fact that there is basically no land in Singapore that can support traditional farming of meat products. So it is a matter of national security, albeit not a super serious one, given its widespread trading partners.

The vascular system: I was fussing with network cables and stuffing them into those cable organizer tubings. And I wondered if there might not be an easier way to organize wired information flow to multiple devices. Then I thought about nerves and blood vessels and regretfully concluded that if biological systems couldn't resolve it without a mass of tubes and wiring either, then this was probably the best that could be achieved. It occurs to me, that when lab meat afficionados boast that they are producing 100% edible product, they are omitting all the equipment that must be utilised to support their endeavors. The vat is equivalent to the skin, the aeration equipment to the lungs and so on and so on. (Edit: Someone in comments pointed to all the disposable gloves to factor in - like shed skin cells. lol) And while it is true that we do not eat bones and hooves, these are useful byproducts used to make bone meal for fertilizer and other uses. What is the leather industry going to do? Rely on plastics?

I know some people with backyard meat factories. all their facilities need is crop waste and water and they use the byproduct to fertilize their garden

i remember how stem cell originally has the potential to heal internal organs for example heart, kidneys without requiring extensive and expensive operations...imagine all that billions are focused on just that...

My family and I will Never eat this chemical filled garbage.

Honestly reviewing the landscape of future worries and present day and past disasters, I hold lab meat in the same regard as something like AI. There are huge claims of what can be done based off of what’s accomplished on a small scale. AI may have its advantages in some areas, but I’d never trust one doing surgery. Lab meat seems like a great concept… on paper. In practical application it is much more difficult to scale up. There are many variables and not enough solid guarantee to any claim. Our ego to make breakthroughs at any cost is a high risk.

When will humans learn that nature is more intelligent than human ?

A lot of things that are advertised as "sustainable" are actually a fluke. My advice: learn about LCAs (Life Cycle Assessments), how they work and see for yourself. Great video btw

I am absolutely never touching lab grown meat.

It's naive to think that you can perform the functions of a cow better than a cow can, despite their MILLION year track record versus your three decade trial and error sessions failing to get anywhere close. You don't need to reinvent the wheel to improve a car, after all.

Yknow, I always assumed they'd just making horrible flesh abominations that grow like fungus but taste and look like beef.

This is not even counting the amount of resources you can extract from cows besides the meat itself, like milk, leather, etc

Rather that Moore's law(which focuses on transistors in an integrated circuit) have you looked at Wright's law in relation to applications to certain aspects of biotechnology and bio-engineering(which might be more relevant)? This combined with the convergence of technologies that is already currently underway which is described very well by Tony Seba, is hopefully enough to make make you rethink your current position? If not after analysis of Tony Seba's work I would love to know why?

Great stuff. I was looking for specifics about culturing the cells specifically. Biopsy>Induced pluripotency>proliferation in a bioreactor>differentiation, scaffolding, etc.

Something we forgot is that animals are already designed to be efficient at using energy. The only downside is that animals aren't designed to grow as large as we want them to, but that is a lot easier to achieve using medical technology than doing everything the body does in a lab as efficiently as an animal does in the wild.

rule of thumb. Eat whole foods, basically a naturally cow. eat less processed foods, so no slurry flesh.

We should still search for a way to end animal factory farming. It’s simply cruel and a horrible thing to do to billions of animals each year.

Maybe the mistake is that we are trying to make chicken or beef from cells, when what we should be doing is to make something rich in proteins and with great flavor by a stand alone micro organism.

I went out and asked an expert on meat production to comment on this video. She said, and I'm quoting verbatim here, "Moo."

Consumers today “get 80/20 ground beef. It’s 80% meat 20% fat”. Consumers in the future “get 80/20 meat slurry. It’s 80% soy protein 20% cell cultured protein”

Way to cherry Pic and flat out LIE about the information that you've provided.

another video full of cherry picking and misrepresenting studies.... but who is surprised

I lost it at the caviar drenched in orange juice

the cow will be the last to be laid off in its job.

“This is chicken but not as we know it.. I also came to work today with a sniffly nose.. Covid chicken”

Considering the cells themselves will evolve to be better at being lab meat, I think framing this as something we have to overcome completely by ourselves is a bit misleading. Plus, if you believe in souls, the souls of the organisms would do most of the work themselves. As they are still there and have nothing better to be doing than being better at their jobs. Even if they do it unconsciously.

Another huge issue is the fact that the different muscles of the animal develop the way they do because of the varied functions and work the muscles perform throughout the animal’s lifetime. A majority of the appeal with animal meat is the fact that different cuts are fattier, leaner, tougher, more tender, and have different flavors. People won’t want to eat strictly ground meat, especially if it’s expensive. Also, you can get a much higher quality of ground meat for much less money by chucking a halfway decent cut of meat in a meat grinder. I just don’t see anyone but desperate vegans eating cultured meat.

Mother Nature ought to sue "JUST" for their injust naming of "Just Eggs", etc. Abhorrent in all honesty. Just raise cows! Humanely, too. No more factory farming of any animal.

the environmental impact of meat is drastically overestimated. cows consume rainwater and crop stems. the meat industry reuses wasted land and inedible plants

I feel like, in a semi-educated way, that this isn't about the farming we do super hurting the environment but people who have a weird "i like meat but i hate that animals die for meat" complex and want a solution. Sorry ethical vegans, life feeds on life, being alive means harming something else.

Bill Gates is displeased.

The cost is just the beginning, actually. There is more to meat than just fat and protein. Those are integral to our nutritional needs, but there is a lot of important vitamins and minerals in animal flesh that won't be in the lab grown meat. Imagine a "beef" steak, but getting none of the B Vitamins or Iron (just to name two things that would be missing). It would be worthless in a lot of ways.

We shall visit this channel again in the coming years.
