As a big fan of the idea of manufacturing meat in an environmentally sustainable way (and without having to resort to raising and killing animals), reading this article felt as if someone was throwning a bucket's worth of ice-cold water on my face.
According to the article, the barriers to cost-efficient manufacturing of lab-grown meat at large scale are fundamental, e.g., impossible to overcome according to the Laws of Thermodynamics and our current understanding of cell biology and chemistry.
Quoting from the OP:
> David Humbird, the UC Berkeley-trained chemical engineer who spent over two years researching the report, found that the cell-culture process will be plagued by extreme, intractable technical challenges at food scale. In an extensive series of interviews with The Counter, he said it was “hard to find an angle that wasn’t a ludicrous dead end.”
> Humbird likened the process of researching the report to encountering an impenetrable “Wall of No”—his term for the barriers in thermodynamics, cell metabolism, bioreactor design, ingredient costs, facility construction, and other factors that will need to be overcome before cultivated protein can be produced cheaply enough to displace traditional meat.
Is there anyone on HN with deep expertise in this area who can comment on this article's scientific accuracy?
