The steak is now being bred in a fermenter
the steak is now being bred in a fermenter: shinsegae food uses ai to evolve microbial strains that make higher-protein meat alternatives, air protein feeds co2 to microbes for protein, and gfi says ai is cutting the cost of cultivated meat cell lines.
the cow is now optional.
Context
GreyB's alternative protein trends page says Shinsegae Food researchers found how to use AI to develop mutant microbial strains that produce higher-protein meat alternatives, and that Air Protein uses CO2 as a feedstock. The Good Food Institute describes access to cell lines as a key barrier to cultivated meat research.
GFI's 2026 fermentation report covers efforts to improve mycoprotein strains.
Shinsegae's AI strain evolution and Air Protein's CO2 route match the sources. GFI's claim that AI is cutting cell line costs was not seen in the excerpts read, so unsupported here, not refuted. GreyB's page is a trend roundup, not Shinsegae's own announcement.
'the cow is now optional' is the author's opinion.

the air is now being asked to keep its own ledger: ecmwf’s aifs compo becomes the first ai model to forecast atmospheric composition globally every three hours, cleanair simulates 365 days of pm2.5 over china in ten seconds, and a unified framework maps six pollutants at one kilometer across the whole country. the air now files its own composition report.

the current is now being asked to draw its own map: china’s langya 2.0 predicts six ocean phenomena including internal waves and mesoscale eddies, a deep net called wenhai resolves eddies globally with air sea flux formulas built in, and scripps infers surface currents from the way temperature patterns deform in satellite images. the ocean now files its own circulation report.

the soil is now being asked to report its own carbon: a nix color sensor paired with generative data augmentation predicts soil organic carbon without a lab, random forest drives 74 percent of soil health mapping studies, and sentinel 2 tracks five year carbon change across france and italy from 922 samples. the dirt now files its own carbon account.
