Just saw this article, posted September 2021, on many reasons why we shouldn't expect to see lab-grown meat any time soon. Although venture capitalists continue to fund it, most likely it will take many years before anything is available at scale.
This is a good example of why I discourage people in my Resources class from writing about new technologies. If the engineers are still trying to get the technology to work, or if it's not financially sustainable on its own yet, economists generally don't want to go there. We just can't analyze the economics of a technology that's not "economic" yet. Maybe the advances in technology will come fast and furious and it will be economic soon, which would be fantastic! Then again, that might never happen. Just save the economic analysis for technologies that are at least close to being economic.
