I read the linked article and the referenced paper [0] fairly closely, from the point of view of a vegetarian that wants this stuff to work from an animal suffering perspective. Long term, I don't think there are any physical limitations argued for by the paper here, and the report doesn't change my ~50 year expectations that slaughter will be greatly reduced in wealthy countries due to tech impact (of either plant replacement or cultured meat). But, it does present a compelling argument against "right now" technology scaling up. If anyone is selling you "we'll grow it in a bioreactor" without answering the questions of (macronutrient sourcing) and ((immunity to bacterial and viral infections) or (cell density)) then they are peddling fake news.
