we have a phrase 'the best thing since sliced bread', as a tag for some new technology that's really wonderful and revolutionary. It is based on the 1961 invention of the Chorleywood process for making (and slicing) bread. (

The sad thing is, many people of that first generation who so embraced it as the wonder product that it seemed to be, suffered from diverticulitis in the later years, because eating it they didn't get enough fibre.

Needless to say, the issue was addressed in due course (they say), but it points up the unknown risks for early adopters of any new technology, and manufactured meat is a new technology.
From birth, what we eat provides the only building blocks we have for the growth and maintenance of our bodies. Just like our chickens.
Commercial ones don't live long because their feed is formulated to maximize egg production and minimize maintenance. (

What is manufactured meat formulated to do? I don't know. But I do know that 'at least cost' will be part of the equation, and the long term outcomes won't be of interest: the timeframe will be set by whatever the regulatory bodies choose as their test period for new foods, and they will be under pressure to shorten it to a couple of years tops. Again like chickens' lifespan of interest to researchers - up to 2 years. Caveat emptor.
