  • The barrier here is that hundreds of millions of years of animal evolution has extremely optimized their form, and the nature of growing only the muscle cells de-optimizes the system. Animals have immune systems; lab cells have to be kept in a sterile environment, a significant cost. Animals have digestive systems and can power cell growth and all other functions from common plant materials; lab cells have to be fed pre-digested and carefully proportioned material, a significant cost. Animals have circulatory systems that efficiently perfuse oxygen and nutrients, and remove waste; lab cell containers have to be centrifuged in small containers because the forces required in large containers damage the cells. And so on.

    Lab-grown cuts are sold as a luxury good now, and I expect as the price comes down from 1000x animal-grown meat to more like 10x animal-grown meat they will become more widely eaten by rich conspicuous consumers.

    The real opportunity for equal-tasting, cheaper, better for the environment “meat” is development of and efficiencies gained by scaling the lines of plant-based imitations like what Impossible and it’s competitors are doing.


  • Lab grown animal cells will always be more expensive than animal-grown animal cells. Animals have immune systems; lab cells have to be kept in a sterile environment, a significant cost.

And so on.

    The real potential for equal-tasting, cheaper, better-for-environment cuts is in plant-based imitations like what Impossible brand and its competitors are doing.

    These laws banning lab grown cells are banning designer lab-grown cuts as a luxury good. Once that market matures, I am sure the wealthy people who jump on the conspicuous consumption bandwagon will not have any problem getting the law repealed or exceptions carved out for them.


  • An economic podcast I listen to has covered how much foreign investment the US net trade imbalance has led to, for exactly that reason: foreigners had dollars from US entities buying more stuff than they sold, those dollars had to come back to the US, and investment ended up being a huge way that happened. If the trade imbalance actually reduces, likely that investment rate will be the first thing to drop. We’ve already seen hints of it with softened demand for Treasury bonds.




  • Their belief in MAGA is filling some deep psychological need. Logical reasoning around the belief is irrelevant because logic can’t activate whatever social buttons are being satisfied by their engagement with the MAGA movement.

    Research trying to figure out what makes humans susceptible to this kind of stuff and how to protect each other was a hot topic, but then Congressional Republicans launched harassing investigations into everyone in the field and the institutions that supported their work, and of course the current executive branch has entrenched that fear. Gotta keep the victims coming to the grifter trough.
