I initially thought this was cultured meat.

So my response is about that.

It's bad because growing cells from scratch will inevitably suffer more losses in production than simply feeding a cow soy and letting it graze grass on lands where fields aren't growable.

You need to first grow something from which you will extract raw resources for growing meat. Then you need to extract and grow the cells. And then structure them. All of this requires additional logistics, energy, manpower and sterile environments to work.

This is inevitably going to be more expensive for resources and energy which means for the environment.

And there's nothing that can fix it. We will sooner make conventional meat production more efficient and better regulated than make this meat efficient.

Its like saying that synthesizing a drug from 7 different chemical reactions or harvesting it directly from a growable plant will be more efficient. It will never be.
