I agree with your analysis but this sentence seems a bit off:
“At some point down the road, we will be able to get perfectly marbled, perfect cuts, of steak for, essentially, no cost”.
No cost, hard to believe...
The marginal cost of just about everything is going to asymptote towards zero. All aspects of production, including the construction of machinery for production, and extraction/recycling of raw material, are going to be fully automated, and all of the software needed to drive it will be freely available. This is talking 50+ years from now, but we are clearly heading in that direction.
Of course, this raises an interesting question. If the cost of everything is asymptoting towards zero, what does the word “cost” even mean? How can money serve as a token of past labor, when almost everything that we consume has no significant labor cost? One way or another, we are going to have to start addressing such questions, and these won’t be just long-term issues — within 10 years we are almost certainly going to start seeing a critical shortage in the demand for labor, worldwide.
Going back to the question of meat: I have little doubt that, say 70 years from now, we will have meat growers in our home, capable of creating perfect meat every time, and there will be virtually no costs associated with using it.
