How about we leave the silk worms alone.

Pretty rich coming from someone sending virtue signals from a device I presume isn’t constructed from twigs and berries. Must be difficult as a person who doesn’t exploit the biosphere.. you’ll have to let us know how you mastered photosynthesis.

I don't eat meat and don't drive cars. How about you?

Silk worms would starve to death if left alone.

Well said, friend. That is an important aspect of the Way. We must be gentle with our mother Earth in order to compassionately harmonize with future generations' happiness. But what I really, really want is hemp clothing. When I was in Atlanta in the 90s, there was a hemp shop, where I bought the best jeans, shorts, and hats I've ever had. They got nothing but more comfortable over time, breathed excellently and neve…

Could it be that it is more sustainable to have them as blends?

I doubt it. I'm pretty sure the % cotton would wear out much sooner, but that's just my intuition.

Cell-free synthesis is the next step. Theres slow progress, but very interesting operational models if it works.

Cell-free synthesis is really nice for R/D (it's fast!) but honestly kinda sucks for producing things. Cells have a really nice property of making more of themselves for the cost of basic chemicals (salt, sugar, nitrogen).

TXTL also can be pretty finicky generally - cold storage is required, have to store chemicals separately, ribosomes tend to fall apart and not get recycled, etc. Cells will heal themselves perfectly (sometimes too perfectly, kicking out your construct)

I first read about industrial use of spider silk literally 25 years ago in Discover Magazine. I'm going to assume it's just never going to make economic sense.

Could you elaborate on why you think so?

It's been 25 years.

from the viewpoint of TFA, meat is a way to (very lossily!) harvest the solar input that goes (over summer months, anyway) into extensive grasslands (inedible by humans in its unbred state), and gather that over several years into a package which (no external refrigeration needed!) transports itself to market/slaughter.

That used to be true when a pig would feed an entire family for a year. You're about 100 years out of date if you think this is still the case.

Yet another instance of how people view the biosphere as a resource to be exploited for their own monetary profit and short-term benefit. That type of logic and thinking is a dead end. I've never had a silk robe and I doubt I would be any better off if I did have one. I'd much prefer clean air, water, and unpoisoned land for growing nutritious food.

Counterpoint: being useful to a more successful species is a staggeringly effective evolutionary strategy. Nature is chock full of symbiotic relationships and it's a perfectly valid ecological niche. Symbionts exist whether or not the host is capable of feeling bad about it.

By becoming attached to such a successful species as humans, any symbiont species has an extremely good chance of surviving for as long as the host species. Including long after they'd have gone extinct naturally.

Most species that humans like or find useful will eventually end up colonizing entire star systems along with us. Those species will continue to live on in their evolutionary descendants long after the sun exapnds and earth becomes inhospitable.

Personally I call that a successful species.

Or we could just leave the worms alone and let them be hunted to extinction by predators or die out in natural climate or ecological shifts over time. I guess that's nicer than species continuity into galactic time scales.

Not GP, but you present a very one-sided view, almost like a commercial for the meat industry.
