It seems you missed the point of the article - which is that given some of the fundamentals underpinning the growth of cells out of the body, with our current and mid-future predicted levels of technology, it is not going to be possible to produce economical meat in a lab anytime soon.
As a no name angel investor, I’ve seen a few of the companies in the report. But also others that are changing the assumptions. So yeah, if you think you are going to produce meat by replicating in vats used for vaccines, then you are going to have problems. There are other paradigms that are more likely to be disregarded out of hand from someone with decades of knowledge, but can work if someone with a bit of naïveté goes forward anyhow.
I mean, AI researchers when I was in college laughed at using any kind of neural network.
And they were right, if you had a short timeframe.
I do think the timeframes are, uh… optimistic like a new SPAC with no revenue.
