Are Factories Better than Cows?

There's a background drone of news stories promoting factory "meat", i.e. cultured GMO cells, as a "green" alternative to beef. I'm an extreme skeptic of the claims made by the scheming promoters of that scheme.

Is a vat of cells more efficient than a cow?

How does a vat of cells regulate its temperature? Probably with a variety of technology, like computer controls, sensors, water jackets to cool the tanks, and HVAC equipment to keep a facility at a nominal temperature.

How does a cow? It just does.

How does a vat of cells eat? I don't really know what they do in this case, I suppose they flow nutrient solution through the vat and also remove the waste the cells produce the same way. The cells are probably free floating rather than fed with a circulatory system. They're probably just goo suspended in a fluid that's mostly nutrients and partly waste. Where does that nutrient goo come from? It's probably sugars and other materials that come from plants on a farm that are highly processed and purified.

How does a cow eat? Well everyone knows that. They either eat grass out in a pasture, or eat feed. Their stomach breaks down the material into nutrients they digest, and the rest becomes fertilizer. A cow converts the plant material almost directly into muscle and energy.

How does a vat of cells fight infection from bacteria, mold, fungus and the like? It probably doesn't. The cells must be cultured in a tightly controlled clean room environment. If a vat gets contaminated, they probably dump it and sterilize the tanks. Where does that thousands of gallons of cell goo go? It's basically like gel meat. It's probably a disposal issue.

How does a cow fight infection? It has an immune system.

I am extremely skeptical of the claims that these factory type food production systems like vat "meat cells" and vertical farms are efficient or are better in any way than traditional agriculture, which has its own problems. They are only more efficient at concentrating wealth via government mandated cartels into the pockets of a few people.
